- The Acoustic Magic Voice Tracker™ array microphone exhibits accuracy degradation at clear speech interference levels above approximately 76 dB. This is normal behavior for non close talk microphones. However it should be noted that the Acoustic Magic Voice Tracker™ array microphone has significantly better noise canceling capabilities under the above test conditions than any array microphone previously tested. Other array microphones generally fail (accuracy results below 65 percent) for clear speech background noise above approximately 64 dB.
- The VoiceTracker™ is effective well beyond the two foot limitation of previous generation arrays.
- When LDS™ is engaged, recognition performance in an environment where noise is coming from behind or from the sides of the microphone is improved by several percentage points.
- When training is performed in a noisy environment, accuracy reduction caused by interfering speech behind the talker is only a few percentage points.
- Ambient home office room noise.
- Ambient noise with clear interfering speech added (CNN Headline News) at normal listening levels (72 to 76 dB) and high-volume listening levels (82 to 86 dB).
- Interfering speech located eight feet behind, eight feet to the side, and eight feet in front of the array.
- User training in low noise and high noise environments.
- Voice Tracker™ microphone operated in various combinations of its four modes.
- Splitting the speaker output 3 ways: running one connection to the speakers, one to the first VTII and one to the second VTII. Electronically, this may have caused an impedance change, but it did not impact the effectiveness of the echo cancellation.
- I used Y-connectors to blend the mono signal from each VTII into one signal. I was careful to use mono adapters to bring the two mono signals together into a single mono signal. I used the line-level setting on the VTII in order to have the strongest signal.

The Voice Tracker™ array microphones have proven to capture the instructor audio across the front of the classroom and also to capture the student’s questions and answers.
We have found the Acoustic Magic Voice Tracker to be an effective microphone to use in our classrooms as part of our lecture capture technology. The arrays have proven to capture the instructor audio across the front of the classroom and also to capture the student’s questions and answers. As a community college our typical classroom size is 32’x45’ and our experience is it captures the room audio very well. They have been easily mounted from the ceiling and placed on the desktop. It allowed us to move away from wireless lapel type microphones and all of the problems they entail. We have about 60 rooms equipped this way.

Tulsa Community College is using the Voice Tracker™ array microphones with Anystream/Echo 360 automated lecture capture system.
The microphone gives our nursing faculty the freedom of capturing lectures without worrying about audio issues. The microphones have also been useful in capturing presentations by speech students. The Voice Tracker™ allows the presenter to have a range of movement without worrying about technical glitches. We've deployed the Voice Tracker™ in 12 classrooms and they have been highly reliable with our automated lecture capture systems. They are more fool proof than any other microphone system we have used over the years.

Chris Austin uses the Voice Tracker™ Array Microphone for recording in combination with Camtasia Software.
I've been recording live classes, meetings, and presentations for several years using Camtasia Studio and a variety of microphones. In an attempt to accurately record the presenter or instructor along with the questions and comments of students and audience members, I've used wireless microphones, shotgun microphones, and multiple microphones mixed together with an external mixer. Some solutions were simple, some complex. But none of them came close to the results I'm now getting with the Acoustic Magic Voice Tracker Array Microphone. It's incredibly simple to set up and it does a great job of capturing the voice of the instructor during the lecture and the comments of the students without the complexity and expense of a multiple microphone setup or the massive background noise of other solutions. I really wouldn't record a live event without it!"

Lory E. Watkins uses the Voice Tracker™ Array Microphone in combination with the ClearOne XAP 8000 for picking up students' questions in large classrooms.
Picking up questions from students in our classrooms has always been a problem even though we have tried many approaches such as PZM microphones on the tables, push to talk microphones mounted on the tables, and microphones hung from the ceiling. We recently installed Voice Tracker array microphones on the ceilings, and the operators seem to like them for picking up questions from the students.
We are using the ClearOne XAP 8000 to accomplish acoustic echo cancellation. We haven’t had any problems with the ClearOne Automatic Echo Canceller and the Voice Tracker mics. They work fine together. The ClearOne also provides level control, filtering, etc.
The XAP 8000 provides phantom power, which needs to be turned off because the Voice Tracker gets power on a separate cable. (If the phantom power is turned on the Voice Tracker makes one hell of a noise!) The inputs to the ClearOne are via Phoenix block connectors and we came out of the Voice Tracker using Belden 9451 cable and into the ClearOne unit.

We are capturing some of our classes using Sonic Foundry's MediaSite.
We are a higher education institute that offers classes from multiple universities and colleges in the state of South Carolina. We were using wireless microphones, but found that the student responses couldn't be heard. In a lecture class that's fine, but so many classes now are discussion and group work, we needed a way to capture that audio. In addition, it frees the instructor from the podium, or having to remember to turn on the WL mic. Finally, I believe the money I save on batteries for the WL mics will pay for the purchase of the Acoustic Magic Microphone and I don't have worry about batteries dying during the lecture.

Dr. Melanie Plett uses the Voice Tracker™ Array Microphone for recording class session for remote web conferencing.
We are using two Acoustic Magic microphones along with a lapel mic and an inexpensive audio mixer to mic our classroom for use with web conferencing software. This allows students to view class from a remote site, and also allows us to record our class sessions. We have found that placing two Acoustic Magic microphones in the front of our classroom allows students to be heard from anywhere in the classroom if the student speaks up.
Since the instructor often has his/her back to the microphones, and since it is imperative that his/her voice is heard, we have determined that a lapel mic is helpful, though not absolutely necessary.

These are working great in our lecture capture classrooms.
We had been using lapel and handheld mics for the instructors, plus your mics for the audience. However, when we switched to Panopto, we re-evaluated our mic installs and found that we could better mic the whole room with just the Acoustic Magic mics - once we had it set on the right configuration option. We are well pleased! This will be our 7th lecture capture room and we are looking at doing probably 3 more this summer.
AcousticMagic rocks!

Mark Hayward of California Medical Devices uses The Voice Tracker 1 to record the audio portion of a prenatal ultrasound exam.
We have installed the Voice Tracker 1 along with a Sony MCS-VRD compact DVD recorder to TOSHIBA Ultrasound systems sold to sites in the OG/Gyn market. The purpose is to record the both the audio and video of the ultrasound exam to DVD for either client or physician review. The Voice Tracker 1 enables the audible Doppler Heart Tones to be recorded, along with both the narration of the ultrasound technician or physician and the comments and emotions from others in the exam room. Prior to the advent of the Voice Tracker, this special ultrasound dual recording capability onto digital media was not trivial and took a bit of a Rube Goldberg setup of mixers, microphones and cables. By contrast, the Voice Tracker was a snap to install. The Voice Tracker was more than sensitive enough to capture voices clearly from all areas of typically-sized exam rooms. Back to the Client/Patient, the recording makes it possible for them to relive the sound of the heartbeats and tech/physician comments, not only over and over but also with significant others. This recording helps provide the patient/client a new sense of appreciation and responsibility for their pregnancy and a likely increase in the quality of prenatal care.

It is critically important for a physician to work hands-free in his environment, so that his main concern is only his patient. The Voice Tracker™ enables medical practitioners to use voice recognition software, such as Dragon Naturally Speaking™, to enter information into Praxis. The Voice Tracker™ is the first array microphone I have used that works effectively in a physician's office.

Harry Baldinger is a medical doctor as well as a Reseller/SW Developer/Trainer of IBM's ViaVoice SW. Harry has been using the Voice Tracker for 6 months.
The Acoustic Magic desktop array mic with USB, is a wonderful tool to enable voice dictation for professionals like doctors and lawyers. It works extremely well with IBM's ViaVoice Pro version 10 speech recognition software. It's advantage over other input devices is that it allows the user to sit back at the user's desk, moving with the normal desktop flow of papers, leaving your hands free. As opposed to some wireless headset devices, the user is not wearing any transmitting electronic gear on or near the user's ears or head. It does require a relatively noise-free environment to work optimally. This can be easily achieved in any office, even a busy office, by simply closing the door.

Courtroom/Deposition Recording Microphones
Mario Perez uses the VoiceTracker™ for deposition recording .
Anytime we have recorded a deposition in the past our attorneys would complain about the audio levels, and to be honest it was horrible. Our office only handles criminal matters and it is very common for deponents to muffle their voice or speak in a very soft voice, because of embarrassment. I would have to spend countless hours in Adobe Soundbooth trying to adjust the levels to compensate for voice fluctuations. To fix this problem we had tried a number of different microphones, including the big name expensive units. Since we switched over to the VoiceTracker™ all those complaints have stopped. This microphone doesn’t seem to have a problem picking up everyone in the room, even if they are whispering on the other side of the room. The installation of the microphone was very easy and the amount of time I have saved in post production is incredible. So much in fact, I’m currently switching all our microphones to the VoiceTracker™.

Lynda Batchelor uses the VoiceTracker™ for courtroom recording.
I use the Acoustic Magic mic daily (along with the FTR digital recording software) to record depositions, hearings, teleconferences, etc. I have used many different kinds of microphones in the past, in all price ranges, and the Acoustic Magic mic is by far the best of the bunch. My experience with the Voice Tracker™ is that it hears everything better than I do. For one thing, it's usually better situated in the room (I'm at an end of the table whereas it's smack in the middle of the table). Anyone that's difficult to hear in the room is always clearer on playback, thanks to the mic.
Because it scans toward each speaker, it picks up each speaker with the same intensity as their speech. It picks up the speakers who are talking over the main speaker, and it even picks up people who are located behind the microphone!
The Voice Tracker™ reduces background noise very effectively. I had one obnoxious situation with an overactive heating system. The Voice Tracker™ minimized the noise from the heater, and it turned out that I could understand the speaker upon playback better than I could hear the proceedings on-site.

Jeff Styles uses the VoiceTracker™ connected to the PA system for Comissioner's meetings.
We recently installed a microphone system in a old historic courtroom in Graham, TX (Young County Courthouse) and the Voice Tracker accomplished our goals with great success!
The courtroom is used for Commissioner's meetings as well as trial proceedings, so standard cardiod microphones were still required at the Judge's Bench and Witness stand. However, in the commissioner’s meetings, the participants disliked having to “lean up to the microphone” during discussion, so we installed two Voice Tracker microphones on each side of the room and connected them to the PA system.
As a result, the county commissioners and/or meeting participants no longer have to lean up to handheld microphones to be heard by the rest of the audience. The commissioners/participants now simply speak in a normal tone of voice and never have to move! The Judge, as well as many who have attended the commissioner meetings and/or court trials, have expressed their amazement at the capability of a microphone to pick up someone’s voice so far away and still be heard so well through the PA system. The judge’s secretary has already purchased additional Voice Trackers for other rooms.
A modification of the cable provided with the Voice Tracker (with 1/8” connections) was required in order to connect to the XLR Balanced Line input on the PA system. Additionally, since the PA system provided phantom power to the cardiod microphones at the Judge’s Bench/Witness Stand, an external phantom power supply was purchased to avoid the “humming/buzzing” sound when phantom power was turned on in the PA system.
We are completely satisfied with and strongly recommend to anyone the Voice Tracker Array microphone from Acoustic Magic!

Board Room Recording Microphones
Powerhouse Dictation Systems uses Voice Tracker to cover entire rooms for Board Room Recordings.
As a company specializing in both digital dictation and meeting recording solutions, we are constantly looking for ways to improve the quality of recording the audio component of meetings. We came across the Voice Tracker through WinScribe NZ and have never looked back. We have in excess of 100 units recording meetings and consultations in executive boardrooms across the country.
The Voice Tracker is generally mounted on the ceilings or walls of the rooms, positions to cover the entire room. In some cases where the rooms are very large, we install two units at either end of the room. Our Audio Visual resellers enjoy the ease of installation and setup. Using either WinScribe or Philips systems, we are able to recording the meetings in high quality formats and then either send for transcription or archive for future access. Since using the Voice Tracker, we have not had the need to search for alternative microphones other than delegate units for our applications.

The Voice Tracker I records even the softest speakers at our school board meetings.
I just wanted to tell you that we—like all your other customers—are THRILLED with the Voice Tracker I microphone!
We had our school board meeting last night and the microphone recorded even the softest speakers. Not only is this a huge technological step above the cassette tapes but it gives us a so very much more effective and productive final product. Thank you all for producing such a gem.
The school board meeting is held in our school library which is a trapezoidal shape, approximately 42’ x 49’, is carpeted, has some walls lined with books, some with windows, and some diagonally placed bookshelves that add more angles. It is heated with a blower fan that creates great white noise when it kicks on.
Last night we had 5 of the board members, the superintendent, the principal, and the business manager as the main participants, with 8 to 10 people in the audience Three students, a teacher, the maintenance supervisor, and a community member made statements/presentations.
We just used the free version of Audacity version 1.3.14-beta (Unicode).
Thank you again, Bob for solving so easily an issue we’ve been fighting with for way too long.

Using the Voice Tracker Array mic for Skype conferences
"We use the Voice Tracker in our meeting rooms for Skype conferencing. We experiemnted with quite a few different mics but I knew we needed an array mic unless we were going into the very expensive systems that I had used in the UK. I set our Voice Tracker up in our largest meeting room and it performed very well, with good voice clarity. So now I decided to get 2 more for the slightly smaller meeting rooms."
"It's a very good product and well worth the price."

Mike Lanthier is President of Harcourt Industries, a digital recorder and speech recognition reseller.
We have finished testing the Voice tracker with good success. We noticed that the settings are important for clarity and voice recognition. It worked best with LDS off. We were particularly interested in attaching the Voice Tracker to Olympus recorders so our customers could record an entire room. We tested it with the DS-3000, which has a 3.5mm external microphone jack, as well as a DS 320. I was impressed when the Voice Tracker picked up conversations in another room some several yards away and walls between.

We were all extremely impressed by it. We have it picking up audio in a 50- person conference room from a corner of the room for a remote connection to Philadelphia, and our guy in Philly can make out every sound in the room. It is far superior to the experiences we've had with Polycom audio units costing 20 times as much. That's a terrific product you've got.

Sally Goldberg is a Documentation Specialist and Remote Meeting Facilitator at Flink Ink.
We recently purchased a couple of Voice Tracker™ array microphones to enable us to use Voice-over IP for remote meetings using Centra Symposium internet remote meeting technology in a group setting. The Voice Tracker™ was recommended to us by Centra as the best array microphone available for conducting an internet meeting where many people were meeting in a conference room with one PC and a projected display of the screen.
The Voice Tracker™ was good at picking up several people's voices in a group across a table and could be clearly heard when we conducted a presentation from Ann Arbor, Michigan that was broadcast over the internet to a large group in Frankfurt, Germany. We are very satisfied with our purchase of this microphone and with the excellent and fast service provided by Acoustic Magic.

Kevin Masui of Ascolta, a Cisco Learner Partner of the Year in 2007
So far Voice Tracker Array mic is the best mic we found to pick up the instructor and students in a large classroom. We use it for our WebEx classroom training sessions in which some students are in a classroom and others are attending from their office or home. We tried a wireless lapel mic at first but that didn’t pick up the other students when they had questions, so the remote students couldn’t hear the questions being asked in the classroom. This also brought up the complaint that classroom students could not hear remote students so we investigated in a speaker/mic combo. We tried one that looked like a polycom conference phone but it only worked well in a really small conference room.
We are currently experimenting with the Acoustic Magic Mic with a Sony external speaker. We found a USB Sony speaker that plugs into the instructors laptop that for some reason doesn’t produce feedback when the WebEx students are talking.

Chris Dalansky uses the Voice Tracker Array mic to enhance operation of the Sony PCS-TL33 VideoConference System
The two Voice Tracker array microphones are hooked up to two Sony table top video conference units that are in two student conference rooms. The rooms are roughly 15'x15' and, depending on the number of occupants, have really pushed the Sony's built in microphones to their limit.
We were looking around at various condenser mics but were having some trouble finding ones with 1/8" plugs or powered XLR. We have a larger conference /class room that uses two Voice Trackers. We took one of the Voice Trackers out to test with the Sony VTC and it worked very well. We also liked the choice in mounting options that the swivel base provides.

I have used Dragon NaturallySpeaking on a daily basis in my work as a securities litigator for at least a dozen years. During that time I have experimented with many microphones looking for the optimal combination of accuracy and comfort. I have at last found that optimal combination in the Acoustic Magic microphone array. In an office environment where external noises can be excluded (such as by closing a door) Acoustic Magic is as accurate as the best wired headset microphones (and better than wireless headsets), but without the inconvenience and discomfort of wearing something on your head/ear. I heartily endorse Acoustic Magic for any serious user of voice recognition software in such an environment.
Al Ducharme used Voice Tracker microphone, integrated with Tegrity software for distance learning.
At the University of Central Florida, we use Tegrity to record approximately 300 sessions each in the College of Engineering and Computer Science. We have used several high quality USB microphones over the past 2 years with limited success. One of the problems we were having is low audio from the instructor and absent audio from students. We were considering an expensive traditional audio system with hanging room microphones and wireless instructor microphones. Fortunately, we discovered Acoustic Magic before we made the purchase. We tested the Voice Tracker array microphone, and were amazed to discover that it could pick up students talking in almost a whisper 20 feet away. In addition, the instructor audio contained little noise and allowed the instructor to move about the room without the need for a separate wireless microphone. We feel confident that the Voice Tracker will meet our needs and have decided to use it exclusively in all of our recording classrooms. The description of our test is as follows: We positioned the Voice Tracker microphone on the instructor desk at the front of a 25’ x 25’ classroom directed towards the students. The microphone was connected to the recording computer using the USB adapter supplied by Acoustic Magic. Students were positioned at 10’ and 20’ distances from the microphone and the instructor was behind the microphone sitting at the desk at a distance of approximately 2’. A series of tests were conducted simulating a typical lecture. Phrases were repeated three times, once in a very quiet voice, once in a normal voice and once in a loud voice. The test demonstrated that the Voice Tracker microphone was far superior to the high quality USB microphones we were previously using. The audio from the instructor was recorded with high clarity and low noise and was independent of the speakers voice level. In addition, the instructor could move away from desk without loss in audio quality. The student audio was amazingly clear. Even at distances of 20’ students voicing questions in extremely low voices could be heard in the recording as if they were sitting next to the instructor.
Listen to the audio recording.

Chuck Runquist performed the testing for Naturally Speaking Certification.
I recently tested the VoiceTracker™ array microphone under a wide range of environmental and training conditions.
My overall conclusion is that the Acoustic Magic Voice Tracker™ array microphone represents a significant advance in technology in far field/array microphones and demonstrates capabilities that are superior to previous array microphones. Properly set up, tuned, and enrolled under Dragon NaturallySpeaking version 6, the AcousticMagic Voice Tracker™ Array Microphone is highly recommended for speech recognition. The accuracy performance of the Voice Tracker™ Array Microphone equals that of close talk headset/microphones, provided that it is used under normal or moderately high noise conditions.

I have been using voice recognition software for several years and found the headset microphone far too confining. I have utilized a number of other desktop microphones including the GN Netcom Voice Array. None of them even comes close to the recognition results that I obtain with the Acoustic Magic Voice Tracker™.
My search is finally over! I feel confident that this is the last microphone that I will need to train - so much so that I have deleted all other microphone profiles. I can think of no greater compliment!

Stephen F. Zeigler, Ph D. is CEO and Founder of SpeechStudio Inc.
The Voice Tracker™ provides just the technology our customers need, and will fit perfectly with SpeechStudio Suite.
SpeechStudio began in 1998 driven by the vision that microphones could track voice for individual speakers. Such technology was already available to our military and intelligence customers. SpeechStudio has built extensive tool support for prototyping, developing, debugging, testing and delivering voice command and control - betting on the future of tracking microphones. It looks like the Voice Tracker™ is just what we have been waiting for.
We tested Voice Tracker™ with our SpeechRunner debugging and testing tools and found that it can perform as well as the best headset microphones, especially considering that headset microphone positioning can be a big factor in real use. In short, in medium- to low-level noise environments typical of an office or home, the Voice Tracker™ gives its user the freedom to give voice commands from two to ten feet away.
We plan to resell the Voice Tracker™ with SpeechStudio Suite. We are building special support into our v3.6.2 release to help our customers handle the unique challenges of this new technology. For example, the Voice Tracker user may be too far from a computer screen to get normal visual feedback of recognitions; also, Voice Tracker™ is so good that users may come to forget that it is always listening to them, and may generate commands from casual remarks. SpeechStudio is using its long experience in both telephony and command and control to help solve these issues for our customers.

I recently purchased the Voice Tracker™ product for use with our PowerTrieve technology. Our users ask PowerTrieve database query questions using their voice. They definitely do not want to put on a headset microphone to just ask a few questions. One of the noisiest environments is my office, because I have an A/C system that blows air into the office and makes a terribly loud noise when it is running at high speed. Other far field microphones that I have tried will fail every time when this thing gets going. The Voice Tracker™ is the first one to actually work. We have also tested this with people talking in my office and in many cases it will ignore them and focus on me. Most impressive!

I have tried the Voice Tracker with a number of disabled users, and recommended its purchase. I was very impressed with how easy it was to use the VoiceTracker and more importantly that the voice recognition accuracy was very good. I see this as a very good alternative for people who cannot easily use a headset or don't want to use a headset.

Thank you. I want to mention to you that the combination of Dragon Naturally Speaking 8 and the Voice Tracker™ microphone has given me a new life. I have Parkinson's disease and cannot type anymore. I have used Dragon Naturally Speaking 7 with the headset which is included, and I found it too irritating to use the headset every time I wanted to type. Also the voice recognition software made so many mistakes that I was ready to scream from frustration. I did not know whether it was the microphone or the software or both.
I then ordered the new software (which has just come out) and in reading the manual it mentions an array microphone. I looked on the Internet and discovered your web site and this microphone. There are no words to describe how thrilled I am with the combination -- I do not have to yell, I do not have to put on a headset, and the software makes few mistakes it's incredible!
I thought you might want to know
Thank you so much for your assistance -- and for giving me a new life!

I can't begin to tell you how happy I am with the quick response and the quick turnaround in getting a replacement microphone. My sister and I are both disabled, so a good, quality microphone is absolutely necessary for speech recognition. The new one works wonderfully.
Please do feel free to use my comment about your company. The Acoustic Magic Microphone is no less than a miracle for someone like me, so if my comments can help you, that makes me happy.

After testing the Voice Tracker™ in a real home environment, we are very impressed with the possibilities of using this device for home automation. We installed the microphone in a 17ft by 22ft family room and connected it to our HomeSeer automation software. From any seating position we were able to give voice commands to control the television, control the lights, etc. It even worked with the television on! For installations where voice recognition is required in a single room, this is an excellent low cost solution.

I recently installed a Voice Tracker™ in my home to evaluate its performance, and I have finally found a microphone that works exceptionally well. I have been using Hal for the last several years and have had some challenges with it understanding me when I used various brands and models of conventional microphones. I found that I had to repeat voice commands several times in order to be understood.
With the Voice Tracker™, Hal 2000 understands me the first time, from anywhere in the room, even with the stereo or TV turned on. I can speak in a normal voice, without shoutiing.I purchased a second Voice Tracker™ and will shortly purchase a third.
I plan to bring prospective clients to my home to demonstrate the Voice Tracker™/Hal 2000 combination.

I received my voice tracker in the mail a couple of weeks ago and I'm very pleased with the device. Here's my review if you're interested:
A few weeks ago I decided to go ahead and order the Voice Tracker array microphone. It arrived in the mail, and it was one of those times like Christmas where you tear open the packaging and behold something shiny and new.
After doing some testing I can say that I'm very impressed with the technology. Acoustic Magic has done some very good work on this product, and I'm happy with my purchase.
The first test I did was using the USB connector, which I figured would have the best quality. The results weren't very good: Only 75% accuracy with a command and control grammar from 12 feet away in the kitchen. Perhaps the output was too weak at 12 ft (see below).
The next test I did was with the standard microphone Jack set at about a 15% input level. I arrived at this setting by using sound recorder and testing what the audio coming in at 12 feet sounded like, which even at 15% I felt was louder than the input that was coming in through the USB connector. (Even with the USB connector's volume set at 100%)
The results of the test was 92% accuracy, which is pretty good considering the distance.
The final test I did was setting the microphone input to about 30%. This resulted in only 1 error out of 40, for an accuracy of 97% from 12 feet, which I was extremely pleased with.
There were still some frustrations, such as it interpreting my saying "17" as "70" more often than not, but overall I can't complain. The other thing to realize is that I'm using XP's voice recognition, which is circa 2001, AKA SAPI 5.1. Perhaps if I were to repeat the test with SAPI 5.3 in Vista I would have more luck with the 17 VS 70 problems. My hope is that Windows 7 will include another update to SAPI, but only time will tell.
Anyway, I am extremely pleased with the results. Thank you Acoustic Magic!

Stan Taylor Uses the Voice Tracker™ Array Microphone with Dragon Dictate 2.02
My Acoustic Magic Voice Tracker™ Array Microphone arrived today and within minutes was up and running ready to create a New Profile in Dragon Dictate 2.02.
It is working really well and seems quicker to respond than the wire connected standard headset from Nuance.
I am absolutely thrilled with the performance.
A great product from a great company.
Keep up the good work.

Hearing Aid Uses
Using the Voice Tracker microphone with iCom equipped hearing aids in meetings and groups
First off, the output of the Acoustic Magic Voice Tracker is at microphone level. Therefore, you need to plug it into some device that is expecting a mic level input. One such device is the PockeTalker. I've used the Voice Tracker with the PockeTalker and it works great. (Just pull out the mic that comes with the PockeTalker and plug the Voice Tracker into the mic jack.)
Then you plug the IOGear GMBA211 Bluetooth audio transmitter into the earphone jack of the PockeTalker (using a mono to stereo adapter since the PockeTalker is a mono device). Pair the GMBA with the iCom and you're in business.
That should do it. The PockeTalker is a small battery-powered device so is very easy to transport.
You can see/get the PockeTalker at http://www.hearinglosshelp.com/products/pocketalker.htm.You can find the IOGear GMBA211 on-line at prices ranging from $30.00 up to about $110.00.
That should give you a system that will work. How well it will work will depend on the background noise in the room. The larger the room and the more noise there is, the less value the Voice Tracker will be. I find the Voice Tracker works very well in smaller groups in a quiet room.

Using the Voice Tracker I with induction loops in small meetings.
We evaluated it with our Microloop III and Portable InfoLoop induction hearing loop products for small meeting table scenarios. Performance was superior to the boundary conference table microphone. The sound was cleaner, more distinct.
We are now recommending it for small meetings and conference rooms...responses have been positive.

Voice Tracker II
Conferencing Microphones
Voice Tracker™ II used with WebEx, Skype, and GoToMeeting
This is in fact a second order for the Voice Tracker II. We installed the VTII in our Board Room last week as part of an overall upgrade of our A/V system there, and are pleased with the results. We have a second room that we use for company-wide videoconferencing. Our CEO was so pleased after one day using the VTII that he asked me to order a second unit for that room as well.
I will definitely recommend the VTII in any application of this type in the future.

Bruce Long successfully chained two Voice Tracker II microphones together
It is possible to Daisychain two Voice Tracker II microphones together.
In my situation (classroom web conferencing) I needed a little more coverage than a single microphone would cover, but I also needed the echo cancellation to function. I was able to successfully chain two VTII’s together.
I put the VTII chain on one channel and had a wireless headset microphone (for the instructor) connected to the other channel of the stereo line-level input on the computer sound card. The headset microphone was adjusted so that it did not pick up enough classroom sound to create echo.
This worked quite well.

Use of the Voice Tracker™ II’s AEC to reduce interference by TV sound in home automation voice control
I'd like to report my success with using the Acoustic Echo Cancellation feature in the Voice Tracker II in my home voice command system to reduce interference by sound from my TV. AEC is usually used to eliminate microphone pickup of a far end talker from loudspeakers in conferencing. In this case, it was used to eliminate the sound from the TV speaker.
There was a definite improvement in the system responsiveness with the TV playing, although I had to make some changes to the voice commands to deal with a slight delay introduced by the AEC system.
My system will respond to commands like "Watch TV", "Watch Movie", "Dim Lights", "Heat Living Room" but you have to give it a “listen” command before giving it one of these commands. Prior to the AEC, I had to make the listen command fairly long to reduce the chance of false triggering due to noise from the TV. The command was 8 syllables and was "Computer, please listen to me". Even with this long phrase, occasionally it would be falsely triggered from the TV.
With the AEC on, there is no way it will falsely trigger anymore. I recorded what the microphone was hearing with the TV playing loudly and it was practically silent. I changed the listen command to a shorter "Computer listen up". However, I noticed the microphone may cut off the first part of my utterance to it. In my example, it drops the "c" from "computer" and the speech recognition hears "omputer listen up" and doesn't trigger. However, if I simply say instead "Hey, computer listen up" or "Yo, computer listen up" it works great. So overall, it is a really nice improvement.
I have a 5.1 surround system, so 3 speakers in the front of the room, and 2 surround speakers in the back. Next to the couch in the back of the room (with 3 seats) is an end table with the Voice Tracker on it. So if you are on one end the couch you are about 3 feet from the microphone, and the other end you are probably 10 feet or so from it. It works well from all 3 spots when the TV is playing. When the TV is off it can even accept commands from a neighboring room.
The microphone is about 5 feet away from the rear right surround speaker (although the speaker is behind and to the left from the microphones point of view). It is about 15 feet away from the speakers in the front of the room. Without the Voice Tracker I would have to hush the volume a bit before giving a voice command and it would occasionally mistake something playing on the TV as a voice command. But with the Voice Tracker II with AEC function enabled it eliminated the false triggering of commands and allows me to issue voice commands even when the TV volume is fairly high.
Sincerely,

Speech Recognition Microphones (Dictation)
Using the Voice Tracker II with Dragon Naturally speaking for legal dictation.
I recently fell on the ice and hurt both of my wrists so badly that I couldn’t type. I therefore had to use Dragon NaturallySpeaking extensively. I decided to use a Voice Tracker II as the input device and found it to be fantastic! Anyone with hand problems would find this much easier to use than even the best headset. It's like having someone in the room to take dictation for me, and be my hands. The voice quality makes it so easy to train Dragon and has reduced the frustration other people have told me they experienced when using the standard headset.

Hearing Aid Uses
Enabling Participation by People With Hearing Difficulties
In the Fall of 2011 the Church of the Messiah formed a project team to find a way for people with hearing difficulties to participate more freely and fully in discussion groups by hearing more clearly what other participants are saying.
We purchased and are regularly using a Voice Tracker I Array microphone together with a Listen Technologies LT-800 072 Stationary Transmitter (72MHz), four LR-072 Portable Display FM Receivers, a Four-unit Charging/Carrying Case, four headphones and an earbud.
The pre-connected microphone and transmitter are kept plugged into wall power, and the receivers kept charged. The system stays on a serving cart which is easily moved from room to room.
The system has been well received by people with a variety of hearing problems. It can be used with or without their hearing aids.
We have used our system for up to 30-40 people in a variety off venues: e.g. 8 feet high 720 sq.ft. classroom, 21 ft. high 7000 sq.ft. worship/gathering space, 9 ft. high 38' x 22' lounge. It can be used in conjunction with a regular PA system.
