Virtually all of the commonly used microphones employed with personal computers are termed electret microphones and operate by using a permanently electrically charged material which alters its voltage when deflected by sound waves. Generally such microphones include a very small "pre-amplifier" to boost this signal and which requires application of a small external voltage. The alteration of voltage caused by sound waves (an analog type signal) travels into your PC sound card or external sound card and is converted into a digital signal which is interpreted by your PC software. There are, in addition, a variety of microphone types based on the outward design of the microphone:

• Wired headset microphones
• Wireless microphones
• Handheld microphones
• Table-mounted microphones

Rating Microphones: Comparing microphones is a difficult task as objective criteria for such comparisons are difficult if not impossible to develop. Further complicating matters is the likely variability of microphones based on dictation environment, user voice qualities, dictation style, and computer. What we have used to develop our rating for each microphone is admittedly somewhat subjective and is based on a series of factors, including: our own experience in using these microphones* feedback from customers comments and evaluations posted on on-line forums ratings provided by other microphone dealers** We will provide relative rating of microphones using a scale of 1-5, shown visually as follows: Fair Excellent *Our true "proving ground" for the quality of a microphone is our experience on a busy and noisy hospital ward. In significantly quieter environments the differences between microphones can be expected to be somewhat less. **Specifically, we have taken into account recommendations provided on-line by knowbrainer and emicrophones

For those new to speech recognition software, particularly the user planning to dabble with this technology but not necessarily use it regularly or in association with his/her occupation, any of the inexpensive entry level microphones should be fine. The difference in accuracy between these "low end" mic's and more expensive microphone is not huge and for the cost savings, these are very effective. And after all, should you decide to upgrade, you have not made a huge investment in that first microphone. Inexpensive microphones that we recommend and carry are shown below.

Comparison of entry level speech recognition microphones:

Andrea NC 181 and 185 Series Microphones: This is a series of microphones released by Andrea to replace its prior NC series. The 181 series has a speaker for one ear and the 185 has a speaker for each ear. Each series comes in 3 versions.

1. A simple version with simple 3.5 mic and audio plugs (NC-181 and NC-185)
2. A slightly fancier version with a microphone mute switch and speaker volume control (NC-181VM and NC-185VM)
3. A higher end version which includes both the mute/volume controls and also a built in Andrea Pure Audio USB sound adapter (NC-181VM-USB and NC-185VM-USB)

For more information on the differences between the microphones in this series, please refer to the comparison table on our Andrea Microphone Page.

This is a series solidly performing microphone series and in the year or so that they been around we have sold many hundreds of these and virtually never get a return or call with a question. Do we consider this microphone series to be worthy of the "5 Dragons" that Nuance provides in their quality evaluation? Not really. Although the native accuracy of this microphone series is quite good, when it comes to noise cancellation (rejection of external noise) they fall short in our opinion. But they are cost-effective work-horse microphones.

The addition of the Andrea Pure Audio Adapter included with the 181VM-USB and 185VM-USB means that you will not be using your on-board sound card, but rather the included USB adapter. This provides a greater level of certainty that the microphone will be compatible with your PC and also offers the theoretical advantage of doing the analog to digital sound conversion in a more "electrically quite" environment (not inside the less "quiet" confines of your desktop or laptop). Again, this is a theoretical advantage.

VXI TalkPro Express

This is another entry level microphone, like the NC 91, which provides very similar results. Like the Andrea NC91, this microphone will give solid performance with typical accuracy levels in the mid 90% range with experienced users (users who enunciate clearly). It does not have any specific qualifications in terms of external noise rejection, so the performance of this microphone will worsen in a loud environment. This microphone has a speaker for only one ear, has standard 3.5 audio jacks (no included USB adapter or translator), and is solidly built and durable. Although more costly than the Andrea NC91, this microphone has twice the warranty

VXI TalkPro

From a distance, this appears identical to the TalkPro Express. The difference is the presence of VXI's "translator". The "Translator" assures a more consistent performance of the microphone in a variety of PC and sound card environments. To learn more about the translator visit the VXI's Microphone Enhancement for Speech Recognition. This is not the same as a USB sound adapter, but does improve performance. This is a solidly performing microphone, although like the others in this "entry level" category does not show the level of accuracy and noise cancellation as microphones in the higher level categories.

CyberAcoustics

Although we were reluctant to carry these microphones simply on the basis of their incredibly low cost and sense that "they couldn't be good at that price", we had enough customers tell us they had used these microphones and noted good performance that we had to try them out. Our thoughts? These are perfectly good microphones and for the cost, a great value. The only difference between the two models we carry is the presence of one versus two speakers. The microphone element and performance with speech recognition is identical.

If you plan to use your speech recognition software with some regularity, but aren't depending upon it at work or as you write your novel, you will likely appreciate the increase in accuracy seen with the following relatively inexpensive and higher quality microphones.

Comparison of Mid-Level Headset Microphones:

Microphone	Price	Accuracy	Noise Cancellation	Durability	Warranty	Overall Rating

VXI TalkPro UC1	$ 102.95				2-year
VXI TalkPro UC3	$ 109.95				2-year

The Andrea ANC 700 and 750 microphones are identical except that the ANC-700 is a monaural headset (speaker on just one ear) and the ANC-750 is binaural (speaker for each ear). Both employ an "active noise canceling" process to reduce the influence of ambient noise. As Andrea Electronics puts it "At the heart of the Andrea ANC technology is a pair of matched omni-directional microphone elements positioned to optimize noise cancellation and capitalize upon their directional frequency independent characteristics." Neither include a USB sound adapter. It is important to know that when used with Dragon NaturallySpeaking the signal:noise ratio may be slightly less with these microphones but this is a byproduct of the noise canceling process and is not an indication of reduced performance. To read more about the noise canceling process employed by these Andrea microphones, read Andrea Active Noise Cancellation (ANC) Microphone Technology, a white paper provided by Andrea Electronics. We consider these to be strong performing microphones and very reasonably priced. Added performance may be realized when utilizing them in conjunction with an andrea USB sound adapter rather than your PC's internal sound card.

VXI TalkPro UC Microphones

VXI recently released a new series of microphones to replace their workhorse TalkPro USB 100 and 200 series microphones. VXI Corp. is known for creating excellent microphones for use with speech recognition and these new microphones are no exception. All three products in this series are Unified Communications (UC) ready, include USB sound cards with digital sound processing (DSP). Being Unified Communications ready means that these mics are intended for use in a variety of settings, including speech recognition, internet telephony, web conferencing, etc.

This series includes the following:

• TalkPro UC1
• TalkPro UC2
• TalkPro UC3

Overall Rating:
Warranty: 2-years
Cost: TalkPro UC1: $ 102.95 , TalkPro UC3: $ 109.95

VXI TalkPro UC1: This is the simplest of the 3 microphones in this series, but performs identically to the others in all applications.

Features:

• UC-ready headset with USB connection that plugs directly into a USB port on your computer for clear, natural voice conversations
• Digital signal processing (DSP)
• Echo cancellation
• One-touch answer/end controls allow for quick and easy call adjustments
• Improved noise-canceling microphone ensures your software application hears precisely what you say, free of extraneous, error-causing information
• Flexible "stay put" microphone boom stays where put for consistent, optimal voice quality
• Plug-and-play set-up means no drivers or software to install
• Compatible with Microsoft Windows 7, Vista, XP, 2000,

The VXI TalkPro USB-100 and TalkPro USB-200

These are identical headsets with the exception of the -100 being a monaural headset and the -200 being a binaural headset. Both use the high quality Gentex microphone element. In addition, both include a USB sound adapter so these microphones attach to your PC via the USB port and neither depend upon your PC's internal sound card. It is the presence of this built in USB sound adapter that explains the increased cost of the VXI USB microphones compared with the Andrea microphones. By virtue of the conversion of the analog to digital signal being accomplished outside of your PC, this has the potential advantage of leaving you less susceptible to electrical interference which might affect this process if done by your PC's internal sound card - something that might be an issue in user's of laptops. Overall, we have noticed far less compatibility issue with the VXI TalkPro USB microphones compared with the Andrea ANC mics.

Note: The TalkPro USB 100 is out of production and no longer available.

Radio Shack "Sennheiser Knock Off"

This microphone is a somewhat difficult microphone to categorize. The term "Sennheiser Knock Off" is not the Radio Shack term for the microphone, but rather a term coined within the speech recognition community because of its outward similarity to the Sennheiser ME3. This microphone has headband system virtually identical to the Sennheiser ME3 and like the ME3 does not include speakers. While it uses a different microphone element than its namesake, it enjoys surprising good accuracy and noise canceling abilities, almost, but not quite at the level of the considerably more expensive Sennheiser microphone. In our opinion, this microphone is clearly a step above the Andrea and VXI microphones in this category in terms of performance. So what's the problem with this microphone? Here are the issues:

• The microphone boom (the flexible rod extending from the headband to which the foam covered microphone element is attached), is a bit long and not as simple to keep positioned as the Sennheiser microphone.
• The foam cover on the microphone element attaches a bit less securely.

On the positive side, this microphone comes with a long cord and is wired ready for use with a PC and does not need to be used in conjunction with a USB sound adapter (a good idea nonetheless but a necessity with the Sennheiser ME3).

Our take on this microphone? For $39 bucks it's a steal. But if you need the performance, you're better off buy the "real thing" - the Sennheiser ME3.

Special Note: Radio shack has changed their source for this microphone. Although it still carries the same product number, it is a different microphone and does not include the high quality element the previous version carried. The version carried at this site and at Knowbrainer.com is the standard, high quality microphone. Be careful about obtaining this microphone from Radio Shack.

For those that truly depend on speech recognition software and who have the need to absolutely minimize the presence of recognition errors, there are several microphones that we believe to be truly superior for use with speech recognition software. The difference in accuracy and sound cancellation among the microphones in this category is minimal.

Comparison of High Quality Wired Speech Recognition Headset Microphones:

Microphone	Price	Accuracy	Noise Cancellation	Durability	Warranty	Overall Rating
Audio-Technica 8HEmV	$ 129.00				1-year

*The Radio Shack "Sennheiser Knock Off" is included in this comparison table since it is very close in quality to the microphones in this category.

Sennheiser ME3

The Sennheiser ME3 is our personal favorite and considered by many to be the best wired microphone for use with speech recognition software. It is highly accurate and uncanny in its ability to reject external noise.

The Sennheiser ME3 is manufactured in Germany and is made for use with their "Evolution Wireless" transmitter and primarily for stage entertainers. Because it is not made for use with PCs, it has a non-standard wiring arrangement and non-standard audio plug. We sell a specially manufactured ME3 which is made with a standard audio plug which is compatible with the USB sound adapters and plugs into standard PC microphone jacks, although it is not compatible with all sound cards. We recommend using the Sennheiser ME3 with either the Andrea USB sound adapter (our first choice) or the Buddy 6G adapter. The Sennheiser ME3 can be used with other sound adapters (Buddy 5G and VXI Two-way adapter) only when used in conjunction with an Andrea P-100 power plug adapter. Attending to the plug issues and when used with an appropriate sound adapter, this is a superb microphone which is truly the leader of the pack in terms of accuracy and ability to ignore extraneous noises.

One thing to keep in mind regarding the Sennheiser ME3 is that it does not include any speakers - it is purely a head-mounted microphone.

The Sennheiser ME3 is highly durable and has been kicking around the back of the author's backpack for nearly four years now and is still going strong! It comes with a 2-year warranty from Sennheiser.

Overall Rating:
Warranty: 2-year
Cost: $ 189.00 (cost includes ME3 microphone, storage bag and Andrea USB adapter)

Audio-Technica Pro 8HEmV

Like the ME described above, this microphone was actually designed for another application - in this case use with a camcorder. But it turns out to be a superb microphone for use with speech recognition. This is a newer arrival to the speech recognition community and while we are confident that it is the rival of the ME3 in terms of accuracy and external noise rejection, we have not sold it long enough to have a good feel for such things as comfort, durability, and overall user satisfaction.

Unique features about this product include:

• Outstanding accuracy and external noise rejection
• Compatibility with all pc sound cards
• Ability to mount over top of head or behind head

Please note that while the picture seems to show speakers, these are not speakers but rather foam cushioned areas for mounting to the user's head.

TheBoom "O"

theBoom "O"is a headset microphone made by UmeVoice. It is light, comfortable and enjoys accuracy and noise canceling qualities extremely similar to the Sennheiser ME3. Because it is designed for use with standard devices, there is not the requirement for use with a sound adapter, although this might be a good idea if you have uncertainties about the quality and shielding of you on-board sound card. We recommend this and other microphones by UmeVoice with any sound adapter except the Buddy 5G and Buddy 6G. In other words if you want to use this with an external sound adapter, we recommend you purchase the Andrea USB adapter or VXI 2-way adapter.

Although we consider the performance from all of the UmeVoice "theBoom" series microphones to be outstanding, they all suffer from the one weakness of being a bit fragile. Don't step on this one or run it over with your desk chair.

Overall Rating:
Warranty: 1-year
Cost: $ 105.00

TheBoom "C"

This new headset microphone is almost identical to the "O" but includes a speaker for each ear. It offers very high accuracy and noise cancellation. Unlike the other UmeVoice microphones, this particular microphone is compatible with the Buddy 5G and 6G USB adapters, although for those wishing to use it with a USB adapter we have the most confidence in the VXI 2-way adapter for use with UmeVoice microphones in general.

We find this microphone headband to be sized somewhat on the small size, so if you have a large head, you might find it too tight. For individuals with small or medium sized heads this should not be an issue.

Although we consider the performance from all of the UmeVoice "theBoom" series microphones to be outstanding, they all suffer from the one weakness of being a bit fragile. Don't step on this one or run it over with your desk chair.

TheBoom V4

This microphone uses the same accurate and noise canceling microphone element as the "O" model, but is ear-mounted. It is extremely lightweight and comfortable. Please see the note about compatibility with sound adapters described with the "O". We recommend the use of a VXI 2-way USB adapter and not the Andrea or Buddy adapters with this microphone.

TheBoom Quiet

This is a unique microphone is this category. It is a significantly larger and more expensive microphone that is useful in two ways. First, it employs very comfortable binaural speakers which include an active noise cancellation system, so it is particularly well suited for listening to music. Second, it includes a microphone boom which is essentially identical to the boom used in the V4 and "O", so it doubles for an excellent speech recognition microphone. In addition, this is a beautifully packaged headset microphone that comes with both a hard and soft case. That it has a relatively hefty price tag should not be surprising!

Dictaphone PowerMic II	$ 424.00				90-day
Olympus DR-1200	$ 249.00
Philips SpeechMike	$ 279.00
Philips Speechmike Air	$ 499.00
Buddy StylusMic	$ 279.00

Nuance/Dictaphone PowerMic II

This is an extremely high quality handheld microphone manufactured by Dictaphone and now owned by Nuance, the maker of Dragon NaturallySpeaking. This is considerably more expensive than it's rival microphone made by Philips and Olympus (see below). Is it worth the extra cost? Here are three reasons to think it might be:

1. It appears to be slightly more accurate than the Speechmike
2. It is notably more noise canceling than the SpeechMike
3. It is specifically designed for integrated use with NaturallySpeaking and this integration and added functionality is expected to increase with future versions of NaturallySpeaking.

The downside? At this point there is virtually no ability to program complex scripts and assign them to keys, as is the case with the Philips microphone. When used with Dragon 10 and 11 (medical versions only), keys can be assigned to a variety of functions, including direct initiation of any inherent or user programmed command.

Olympus DR-1200

We love the the touch and feel of this microphone. Although it is described by Olympus as have 5 programmable buttons, we actually find that there are 10 buttons which can be programmed for both the Mac and PC. When using this with a PC you can configure the buttons using "Device Configuration Manager" which is downloaded from Olympus. With a Mac, you must obtain the freeware system utility called "USB Overdrive" which allows you to easily assign buttons to a variety of functions with Dragon or other programs. While we love the feel of this product and are very happy with its accuracy, we do not find the external noise rejection properties of this product to be any better than the Philips SpeechMike II (average at best) and somewhat less than what is seen with the Dictaphone PowerMic II. Although you can use the Device Configuration Manager to program functions within Dragon, integration with Dragon is not nearly as tight as it is with the PowerMic. Where this product excels is a) overall ergonomics b) a nicely functioning trackball c) ability to use this with any version of Dragon (the PowerMic II is limited to use with medical versions and d) ability to use it with an Apple computer (along with USB Overdrive to assign functions to keys in the Apple environment).

Features:

• Large multi-functional push buttons with trackball
• Symmetrical and ergonomic design for comfortable hold
• USB direct dictation device
• Symmetrical design giving optimum use for both left and right handed users
• Directional microphone to reduce undesired background noises
• Engineered to work best with Dragon NaturallySpeaking speech recognition software
• Powerful integrated speaker for clear playback

Philips SpeechMike Air

The Philips SpeechMike Air is a high quality handheld wireless microphone that comes in 3 varieties, depending upon your dictation workflow. All three share some great features: high quality performance, wireless convenience, and a sense of extreme quality as it sits in your hand. Our only complaint about this microphone and one which is shared with its wired version, is a relatively poor external noise rejection. It will pick up background noise fairly easily and this may impact your performance with speech recognition software if significant.

Features:

• Superb recording quality optimized for speech recognition
• Trackball for navigation through documents
• Recording control with 4-position slide switch or push button version
• High-end front speaker for crystal clear playback
• 3 function buttons for individual configuration
• Up to 7 hours of recording time on a single charge (2.45 hours for full charge)

Philips SpeechMike III

The SpeechMike III microphones are a series of hand-held USB microphones made by Philips and which comes in two configurations:

• Push-buttons for selection of recording, etc.(3210 model without software; 3215 with SpeechExec Pro software)
• Slider switch for selection (3200 model without software; 3205 model with SpeechExec Pro software)

SpeechMike 3200 & 3205 Price: $ 379.00	SpeechMike 3210 & 3215 Price: $ 379.00

The professional SpeechMike USB microphone takes stationary dictation to a new level. It delivers excellent speech recognition capabilities, an antimicrobial surface for improved hygiene and refined ergonomics for convenient operation.

The quality of noise cancellation and the overall durability of the microphone has also improved. This version boasts up to 98% accuracy when properly used with Dragon.

Use the push buttons (3200) or slider switch (3210) to manage your dictations and the light-weight device will lie comfortably in your hand even during longer dictation sessions. The scroll wheel allows you to one-handed move through forms or documents, while the dust proof optical trackball offers unparalleled navigation accuracy. Control the playback volume directly on the SpeechMike for highest convenience. Excellent sound quality ensures crystal-clear playback, saving time during the transcription process.

Features:

• Noise-canceling microphone for accurate speech recognition results
  
• Integrated sound card and speaker ensuring crystal clear playback
  
• Geared for Dragon NaturallySpeaking speech recognition software

Our take on this product: This is a popular and reliable hand-held USB microphone that works extremely well with Dragon NaturallySpeaking. Although it does not provide the level of integration with Dragon as the Dictaphone PowerMic, using the included software, it is actually possible to do far more programming with this microphone than with the Powermic - but it requires more work on your part. Compared to the PowerMic, this has a nicer feel and the included track-ball tends to be far more ergonomic than the track stick found on the PowerMic. Results (accuracy) with speech recognition tend to be very similar between the two products.

VXI Xpressway*	$ 96.00					16 hr	66 ft	1-year

Comfort: This parameter is obviously extremely subjective and variable from user to user. In general we weight headsets with typical over-the-head mounting arrangements a bit higher than ear mounting (BW900) given that most users are accustomed to the feel of a typical over-the-head arrangement.

Stability: This refers to the tendency of this microphone to remain in place in reference to the user's mouth during movement of head and potentially when assuming a supine (laying on back) position

Price: Prices represent current prices for the microphone, with basic additional hardware if required (both the Plantronics CS55 and Sennheiser BW900 require the GN Netcom rocker switch in order to work with a PC and prices include this). With the exception of the VXI and Revolabs mics, all of these microphones work best when used with an external USB sound adapter. The cost of this is not included in the prices listed above.

*The VXI Xpressway does not come with a base station and must be used with a Bluetooth equipped device or pc.

Sennheiser DW Pro-1 and DW Pro-2

It's been a long time since we've been as impressed with a product. Until now we have considered the Sennheiser BW900 the best wireless microphone for use with Dragon. While we loved the convenience of the Sennheiser DW Office, which allowed seamless movement from the phone to PC, we never felt the speech recognition accuracy nor external noise rejection was quite at the level of the BW 900. Now things have changed.

For any user wishing to go wireless, either for VoIP or speech recognition, and especially for the user wishing to use the same set-up for wired telephone use, this is the perfect product. This DW Pro has all the features of the DW Office and betters the quality of the BW900. It is, in our opinion, an amazing product.

Features:

• Ability to move back and forth between a wired telephone and personal computer with a single button push
• Outstanding accuracy and external noise rejection with speech recognition software
• Integrated USB sound adapter for use with a pc

Comments: Honest to God, we are having a hard time containing our enthusiasm for this product. On the first night I tested it, with a brand new profile set-up on the new medical version of Dragon I witnessed absolutely flawless performance. I then asked my 9-year-old, who is used to hearing dad say "can you keep it down a bit", to come over and be as loud and as obnoxious as he wanted. Not surprising, he didn't hesitate. Amazingly, Dragon didn't hear a bit of it and continued to work flawlessly. The downside of this product? First, it doesn't use Bluetooth frequencies, so you cannot directly pair the headset to your computer. Second, it's expensive. But you are clearly getting what you pay for with this product. By the way, the only difference (beyond price) in the Pro-1 and Pro-2 is the number of speakers. Performance is otherwise identical.

Sennheiser BW900

The BW900 is an ear-mounted wireless bluetooth microphone which includes a highly accurate and noise canceling microphone. It communicates via bluetooth with your PC, with a base station which can connect either to your telephone or PC (the pc connection requires an extra cable) and is also capable of connecting to your bluetooth equipped cell phone. Unlike most ear-mounted bluetooth microphones, the BW 900 has a full length boom and places it's noise canceling microphone adjacent to your mouth.

Unique to this unit is the following:

• Bluetooth wireless connection
• Extremely accurate, noise canceling microphone
• Capability of pairing directly with base unit, bluetooth equipped PC, and bluetooth cell phones
• Hot swappable battery

If it isn't enough that this microphone is lightweight, comfortable and includes lots of unique features, it is among the most accurate headset microphones we have tested and is every bit the match for it's wired Sennheiser rival - the ME3. We were absolutely astounded by the results we got using this microphone with Dragon NaturallySpeaking.

Jabra 9350e

Only the Jabra 9350e and Sennheiser DW office are specifically designed for both telephone and general computer use, without the need of additional cables and switching devices. The 9350e provides for 3 different mounting methods, including a traditional headband, a neckband, and ear mounting method. Further, it is extremely lightweight and comfortable.

How does it perform? We are extremely impressed with the accuracy of this microphone. It appears to be every bit as accurate as our best performing wireless microphones. If it has a weakness it is a noise canceling ability which is slightly less than the BW900 and Plantronics CS70N. Does this mean it has terrible noise canceling properties? Absolutely not! We have found this microphone works absolutely fine with a radio or television playing softly in the background, so in ordinary noise situations it works well. We wouldn't recommend it for use in a loud office situation.

Features:

• Talk time: 9 hours
• Standby time: 120 hours
• Weight: 0.92 oz
• Range: 300 ft.
• Future-proof investment: single headset for traditional and PC phone calls
• DSP and IntelliTone™ for superb sound quality and greater hearing protection
• Noise-canceling microphone for reduced background noise
• LCD display for easy set-up of personal sound preferences
• Lightweight design and three wearing styles: headband, ear hook and neckband

Revolabs Xtag

This unique device is revolutionizing the way we use microphones. It is a wireless microphone which communicates with a small base station which connects with and draws it's power from your PC or Mac computer using an available USB port. The microphone itself measures only 2.5 inches x 0.9 inch and weighs only 0.05 lb (less than one once). It has a range of 20 meters, and uses a rechargeable lithium polymer battery with an 8 hour talk time. The big advantage of this microphone is extreme comfort - you will forget you are wearing it - and a surprising high level of accuracy. The only disadvantage (other than price!) is the relative lack of noise cancellation resulting from its positioning relatively distant from your mouth. This is an outstanding microphone to use in a quiet environment but will provide disappointing results in settings with anything other than mild background noise.

Samson Airline Micro

We continue to test this unit, but our preliminary impressions are very favorable. It is amazingly small and lightweight and yet attaches so securely that use by a fitness instructor is entirely feasible. On the other hand it seems to have the accuracy to allow accurate use with speech recognition software. We have not yet formally evaluated the external noise rejection qualities of this microphone, but in preliminary testing it seems to do fine and was minimally affected by our babbling 8-year old son, a fairly loud air conditioner and other household noises. The external noise rejection is clearly well above average.

We recommend using this device with a monaural USB adapter such as the Andrea USB adapter since it does not have sound out capabilities. This product is packaged for use with professional sound equipment and not a personal computer. The audio output cord has a 1/4 inch plug. We recommend that you purchase a double male stereo 1/8 inch cord if you plan to use this with a pc. We list both the USB adapter and 1/8 inch double male cord below.

Samson Airline 77 Wireless Microphone

This is a unique and highly accurate wireless microphone that provides the best accuracy in the wireless category. It does not include speakers and the transmitter sits on the back of the microphone, essentially near the base of your skull. This includes a good sized transmitter which, in turn, is connected to your PC with a supplied cable. The advantage of this microphone is the freedom from wires and the high accuracy. The disadvantages include 1) It requires daily replacement (or recharging) of the AAA battery in the head-worn transmitter and 2) it is a bit rigid and not the most comfortable microphone we have tried.

Plantronics CS50-USB

This is a comfortable, ear-mounted, wireless microphone which communicates with a base unit which, in turn, is attached to your computer via an available USB port. Although we were skeptical that this microphone would perform so well, it is truly outstanding in both noise cancellation and overall accuracy. The main advantage of this microphone over its rival, the Sennheiser ME3, is the freedom of the wireless connection. It has a 200 ft range and the battery lasts a full 8 hours. The disadvantage, if any, is that it attaches to the ear and based on your ear shape, it may or may not be comfortable. It includes a variety of different ear-pieces and the option of using it as a typical over-the-head headset microphone (follow some of the links below to see options). The battery in the mic unit charges when in the base unit which in turn receives it power either via the USB connection or the supplied AC adapter. Overall, we find this to be an extremely good, albeit pricey, microphone.

Plantronics CS70N

This is a high quality wireless microphone designed for telephone use but easily adapted to use with a pc and with speech recognition software. It somewhat similar in function and performance to the CS55, but rather than using simple frequency filtering has a high quality noise-canceling microphone. Unlike the CS55, this microphone is designed for use only while mounted to the ear. It does not include over-the-head (typical headset) mounting options. It is, nonetheless, highly comfortable and designed for all day use. It works extremely well with speech recognition when used with the bundled GN Netcom SeleCT switch or Zoom Switch. When set up in this way, it can be used alternately with both your corded telephone and PC with a simple push of a switch. This set-up is not recommended for use with home wireless phones. This is the identical microphone set-up sold elsewhere at a considerably higher price!

VXI Xpressway Specification Sheet

Comments: We were skeptical about this microphone given its very modest cost, but were very pleasantly surprised at its performance. Not only is it highly accurate when used with Dragon, but it's also extremely good at external noise rejection. It comes with 3 mounting platforms: an ear only mount, a typical over-the-head mount, and an around-the-back of the head mount. We found the back of the head mounting platform very stiff and uncomfortable (it seems to have been designed for a childs head), but the traditional headset mounting was both comfortable and stable. Remember that this microphone requires a Bluetooth equipped PC (or an adapter such as the Iogear GBU 421 Bluetooth Dongle).

Some users would prefer to avoid wearing or holding a microphone. For some users with disabilities, particularly with problems related to use of your hands the concept of a desktop microphone works quite well. In general these microphones work well, although they share the susceptibility of accuracy falling off as your distance and angle of approach to the microphone vary.

SpeechWare 3-in-1 TableMike (TK03)

This "second generation" TableMike from SpeechWare and is the result of more than a year of the best Belgian engineering and input from a number experienced speech recognition users/resellers including Chuck Runquist, Larry Allen, Lunis Orcutt and Speech Recognition Solutions. While the first generation product was good and clearly on par with other table-mounted microphones, the soon to be released "second generation" 3-in-1 is looking to be nothing less than extraordinary.

Unique to this product is an auto-gain or "equalizer" function in the microphone input volume which will automatically increase the gain as you move further away from the microphone element and allow a workable distance between 10 and 20 inches. Also unique is a digital signal processing built into the circuit board which does an extraordinary job removing external noise. The result is a microphone with a high level of accuracy over a great variation of distances and relative immunity to external noise. In our opinion this is the best table mounted microphone for speech recognition users, unless you need the features contained in the 6-in-1 or 9-in-1 microphone (these offer the same quality with speech recognition software, but other helpful features).

Like the other microphones in the TableMike series, this microphone can be used in one of three modes:

• Speech Red mode (auto gain employed; maximal noise cancellation; working range 10-20 inches; speaker not operational in this mode)
• Normal mode (most realistic sound and noise rejection but auto-gain not operational and working range 2-4 inches; speaker operational in this mode)
• Accessory microphone mode (a separate headset microphone of user's choice can be plugged into microphone jack)

[Note: the 6-in-1 TableMike has not been released as of the time of this edit; it has been extensively tested by the author and is expected to be available in late April of 2012]

This microphone has undergone re-design with the best Belgian engineering and is currently in production in Taiwan. It is expected to be available in April of 2012. It uses the same microphone element and circuit board as the 3-in-1, so provides identical performance with speech recognition software.

Features this microphone has over the 3-in-1 TableMike are the following:

• a longer boom (18 inches)
• integrated speaker with volume controls
• a jack for integration with an optional foot pedal
• an accessory USB jack

SpeechWare 9-in-1 TableMike (TK09)

This is the "grande" of the SpeechWare TableMike series. It uses the same microphone capsule and circuit board as the other members of this series, so will exhibit the exact same accuracy, noise cancellation, and working range. Unique to this product is a number of additional features, including:

• A unique telescoping boom which can vary from 16 to 24 inches
• Two accessory USB ports
• An integrated SD/SDHC/MMC/MS/MSPro/MSPro-HG card reader
• A programmable button which can be used to control other applications

Like the 6-in-1, this product includes a built in speaker, and foot pedal jack to use with an optional foot pedal to control the microphone on/off functionality. Like the other members of this series, the 9-in-1 includes an accessory microphone jack and a sound out jack. This microphone truly has it all!

Buddy USB Desktop Microphone

This is a considerably better desktop microphone than the inexpensive ones seen in electronics stores. We don't consider this to have the accuracy of our better headset microphones, and falls short of the Speechware microphone shown above. It is, however, considerably less expensive than the Speechware microphone and it is notably better than the average desktop microphone sold at your local Best Buy. For those seeking a reasonably priced microphone and needing to keep their hands and heads free, this is an excellent choice.

Important features include the following:

• USB plug-and-play microphone
• Built-in noise-canceling microphone designed for speech applications like dictation and transcription
• Includes FilteredAudio™ technology for highly effective mechanical noise cancellation (Selected Models)
• Configurable microphone buttons:
  Push-To-Talk to hear sound only when button is held or set for mute toggle
• Direct control of the microphone On/Off function in Dragon NaturallySpeaking
• One programmable button simulates keyboard or mouse input for repetitive tasks or to insert text.
• Once programmed, Buddy DesktopMic 7G retains its configuration
• Free MyBuddyMic™ software download allows you to customize advanced tasks to control Microsoft Speech and Dragon NaturallySpeaking
• No need for additional drivers -- MyBuddyMic is optional for most normal operations

Samson Q1U - Balanced Spring Arm Combination

Although we have this listed last, in many respects this is our most highly recommended desk mounted microphone. The combination includes an extremely high quality hand-held microphone with a USB interface and a mounting mechanism which allows attachment to a distant site on on your desk or work surface.

In terms of quality, this is an outstanding microphone. It provides excellent accuracy and extremely high level of external noise rejection. Unique to this set-up is the ability to use the microphone when positioned as far as 12-14 inches from your mouth (we recommend doing the training and sound set-up with the microphone just a few inches from the mouth, but thereafter it can be successfully positioned much farther away during actual use.

Microphones for the iPad

The iPad Headset Adapter - get this first!

Although you can use speech recognition on the iPad with a Bluetooth microphone, this turns out to be somewhat complicated and for the average user seeking improved performance over the on-board microphone, interfacing with the audio jack on the top of the iPad is the simplest and most reliable method to do so. The advantages of using a headset microphone plugged into the audio adapter are two-fold and include:

• Improved accuracy
• Improved external noise rejection

Unfortunately a standard headset microphone made for use with a personal computer or portable audio device cannot be used when plugged into the audio jack on the iPad because the jack has four terminals and plugging a microphone into this jack will actually short out the microphone terminal and the iPad will continue to default to using the on-board microphone. In order to get around this, Speech Recognition Solutions is happy to offer a simple audio adapter that splits the connections within the audio jack into those needed for stereo sound out and those for the mono microphone in. Pictured on the right, this adapter will allow you to use a headset adapter for speech recognition, Skype and other internet telephony applications, and with other audio applications such as Garage Band.

iPad Compatible Microphones

The following are headset microphones that we have specifically tested with the iPad and which we recommend. Keep in mind that for many or perhaps most casual users, the on-board microphone works fine. We have been very impressed with the results using the on-board mic and recommend these products only if you have the need for more intense accuracy, external noise rejection, or desire for the process to be a little more discrete. In general you can talk a bit more softly when using a headset microphone. Remember, you will need to purchase the iPad headset adapter (shown above) in order to use a headset microphone with your iPad.

Hearing is believing: If you want to hear directly the difference in audio quality of the iPad on-board microphone versus some traditional headset microphones, click on the links below to hear some audio examples. We recommend that you play the top recording (the onboard microphone) first so you can compare it with the others. Although you will notice some differences in the "quality" of the sound, the truly monumental difference is the ability of a headset microphones, in varying degrees, to ignore external noise. The on-board microphone picks up almost everything in all directions from the iPad, while the headset microphones barely register the external noise.

[A note on the production of these files: These files were recorded using either the specified headset microphone attached using our headset adapter shown above plugged into the iPad audio jack, or with the iPad on-board microphone (top recording only). All files were recorded in .caf format using the iPad app "Sound Recorder" and then transferred to a pc where they were converted to .wav files using "Switch Sound File Converter Plus". External noise, which is introduced about half way through each recording, is coming from using playing directly in front of the recording subject, at a distance of about 2 ft. and with a sound level of about 65dB as measured at the microphone element.]

Andrea NC 181:

This is a "workhorse" microphone and is Andrea's replacement for the NC91. It is very cost effective and can be expected to give good results with VoIP and speech recognition applications. This basic model includes only monaural sound (only one speaker) and standard 3.5 mm connectors.

UmeVoice theBoom "O"

Unfortunately, we are temporarily out of stock of this item. It is being redesigned and is expected to be available in late April or early May of 2012.

This microphone uses the identical element as the "V4" but is an "over the head" headset microphone. It shares the exquisite accuracy and noise canceling qualities of the V4 and is a clear rival for the Sennheiser ME3, although significantly lighter, potentially more comfortable than the ME3, and with the added advantage of having a speaker.

Other than the different means of attachment to your head, this microphone uses the same element and is similar to the V4 in accuracy and noise canceling abilities. Likewise, it is equipped in a manner similar to the "V4", including the 2.5 mm plug for attaching to most cell phones and a PC adapter for use with computer sound cards and USB sound adapters. The total length of the cord on this microphone when using the connectors as advised below (see the diagram with the description of the PC adapter) is about 72 inches.

This is a superb microphone and priced notably less than its only rival - the Sennheiser ME3.

Additional Information:

Comments: We consider this microphone to be of extremely high quality in terms of performance with speech recognition and equal to the accuracy and noise cancellation of the Sennheiser ME3. Advantages over the ME3 include the presence of a speaker and comfort. Disadvantages include a shorter warranty (only 1 year versus two years for the ME3) and a slight fragility. We recommend you use caution in straightening out the plastic headband as it might snap if pushed too far. This is our highest performing headset microphone when used with the iPad.

Comments: This is an outstanding microphone for use with speech recognition software. Its only rival is the Sennheiser ME3, which is similarly great, but this unit has a few advantages, including 1) lower price, 2) ability to use it on either side 3) ability to use it over the hear or behind the head. In our testing we have found this to be generally comparable to the ME3 in performance. We recommend using it without the foam windscreen. If you have any doubts as to the quality of your computer sound card, or if you are planning to use this microphone with a Mac, we recommend you purchase the combo shown below which includes an external USB sound adapter.

Please not that this microphone has foam-covered pieces on each and and that while these are similar in appearance to the speaker on a traditional headset microphone, these are only mounting/stabilization areas for attaching the microphone to your head. Whether you mount the microphone over the top of your head or behind your head, the mounting areas will best sit in front of and above the level of your ears, generally speaking above the area of your temple on each side. When mounting on top of your head you will notice that better balance will occur if you lean it backwards a bit (not straight up).

If you are in this category and your computer is an essential tool that you can't compromise, you may be particularly sensitive to issues of attachment site, comfort, and connectivity. You may find some of the following characteristics important when you choose a microphone:

• The Sennheiser ME3 attaches fairly rigidly to your head. While this results in a very secure attachment and little likelihood of the microphone element moving away from its proper position, some users find it to be slightly stiff and uncomfortable. Another potential disadvantage of the ME3 is that it does not include speakers, so if you're using it for a telephone substitute, recognize that the sounds will be coming from your PC speaker and not the headset. The Sennheiser ME3 is, however, the leader in terms of accuracy and highly durable.
  
• The UmeVoice theBoom V4 is highly accurate, lightweight, and comfortable. It takes a bit of manipulation to get it attached properly to your ear, but once in position is secure.
  
• The Plantronics CS50-USB has many great features, including excellent accuracy, a wireless connection, and the ability to mount it to your head in a variety of ways. It comes with several different ear mounting schemes and also a traditional "over the head" headset attachment system. As an ear mounted microphone we don't consider it quite as comfortable as the theBoom V4, but the lack of wires is a definite plus!
• The Plantronics CS55 Hybrid microphone is unique in being compatible with both a personal computer and telephone. Like the CS50-USB, it allow multiple means of attachment.
• The Revolabs Xtag is the most comfortable microphone we sell and is the only one that does not actually attach to the head. Rather, it sits either in a breast pocket or hangs from a lightweight lanyard which goes around your neck.

External Sound Cards:

Traditionally, a PC mic is plugged into the microphone input jack on a computer and the analog signal is sent to the computer sound card where it is converted to a digital signal and then used by your software. On some computers, particularly laptops where the sound conversion circuitry is typically integrated directly onto the motherboard, it is thought that other electrical devices in close proximity of the sound conversion circuitry may lead to interference and degradation of the signal and reduction in accuracy. An external sound adapter accomplishes the analog to digital conversion outside of the computer and imports the signal via an available USB port.

The need for an external sound card is variable and depends upon your equipment, the quality of your PC's sound conversion device (sound card) and the extent of shielding within your PC. In most instances a good sound card will serve you fine and you needn't consider an external device. There are a few exceptions.

First, if you are using a Sennheiser ME3, you are using a microphone that was wired for a different purpose and only a few sound cards can deal with the unusual wiring pattern. We know of only one external sound card which will reliably deal with the unusual wiring of the Sennheiser ME - this is the Andrea USB sound adapter.

The second situation in which an external sound adapter should be considered is if you are not using one and don't feel you are getting the accuracy which would otherwise be expected with your selection of equipment.

When considering an external sound adapter, also consider whether you need a full duplex (sound going in and out) or a monoplex device that simply needs to input your microphone signal into the PC. As an example, if you are using a headset that includes only a microphone (such as the Sennheiser ME3 or Audio-Technica Pro 8HEmV) you are better off with a monoplex adapter such as the Andrea USB adapter which will port sound in via the USB adapter, but leave sound out in the hands of the on-board sound card.

These are the external sound adapter we carry and recommend:

Note: All of the USB adapter that are listed as being incompatible with the Sennheiser ME3 will work with the ME3 when used in conjunction with an Andrea P-100 power plug adapter.
