Which Voice Tracker Should I Get?

The question we probably get most often is which Voice Tracker model should we purchase?

Some people think that because the Voice Tracker™ II is newer and more expensive it is “better”. But actually, which one is better depends on the application.

Taking A Look At The New Voice Tracker II, Compared To Voice Tracker I

Here’s a closer look at the new Voice Tracker II, compared to the Voice Tracker I:

Voice Tracker I

The Voice Tracker I is targeted at meeting and lecture recording applications. It has more microphone elements in its array and a wider aperture than the Voice Tracker™ II, therefore, it has longer pickup range. It is a little easier to use than the Voice Tracker™ II (it only has one connection into the PC, which is the analog audio cable to the soundcard) so it requires less IT support.

This is important to schools that may have 50 or more Voice Tracker’s in various classrooms but not a large IT support team. It is also less expensive than the Voice Tracker™ II, which is important to schools with tight budgets and a lot of classrooms to “mic”. It is easy to combine several Voice Tracker I models using a simple mixer or 3.5 mm Y’s.

Voice Tracker II

The Voice Tracker™ II is targeted at VoIP conferencing and distance-learning applications. It has a built-in acoustic echo canceler for those situations where there is not an echo canceler available in the system the Voice Tracker is connected to (or the AEC in the system is not robust). But the Voice Tracker™ II’s pickup range is a little less than the Voice Tracker I, 20 feet in front rather than 30 feet.

Additional Factors To Consider When Deciding Which Voice Tracker You Should Get

There are other considerations that may lead you to choose one model versus the other:

  1. The Voice Tracker I can be used for conferencing if it is connected to a system that has a good built-in acoustic echo canceler (AEC). Voice Tracker I’s have been connected to conventional conferencing systems like LifeSize, Polycom, ClearOne, etc. or can be connected to a VoIP systems with good AEC’s like Zoom.
  2. The Voice Tracker™ II is more portable. It is powered by USB. This (combined with its smaller size) improves its portability since it can be powered from a laptop. The Voice Tracker I must be powered from its wall power supply.
  3. The Voice Tracker™ II has both a USB audio output and an analog audio output. Consequently, several Voice Tracker™ II’s can be combined (like the Voice Tracker I) using the analog outputs connected to a simple mixer or a combination of Y’s. But if the acoustic Echo cancellation feature is being used, each Voice Tracker II must receive a reference sample of the signal going to the loudspeaker. This makes the wiring connections a little more complicated.

How To Choose The Right Voice Tracker Array Microphone

Using the above comparison and factors will help you choose the right Voice Tracker array microphone for you or your company’s needs. Both Voice Trackers are multipurpose microphones. Besides meeting recording or conferencing applications they can be used for hands-free/headset free automatic speech recognition with products like Dragon NaturallySpeaking. The Voice Tracker™ II actually is a little better for this application because its smaller pickup range minimizes spurious words from talkers across the room (if there are any).

Lecture Recording Microphone: Key Equipment For Distance Learning

Many people these days are interested in furthering their education as a way to qualify for the next step on their career ladder or to make a complete career change. Distance learning or online learning has become very popular, and schools use a variety of mediums including teleconferencing to provide course information to students.

Leading Technology In Our High Quality Lecture Recording Microphone

With our scanning unidirectional technology, only a single conferencing microphone is needed, as compared to several microphones that are normally needed for a large room. This enables high quality, complete room coverage more easily and efficiently.

By using a high quality lecture recording microphone like the Voice Tracker to make recordings, universities and schools are able to allow their online listeners to feel as though they are right in the classroom and don’t miss a single word of what is being said by the instructor as well as questions asked by students throughout the room. Our technology effectively eliminates background noise and echo.

Why Students Choose Distance Learning

There are a number of reasons why distance learning (audio and video conferencing) appeals to modern learners, including:

  • They do not have to live in close proximity to the school of their choice. Distance learning opens up more educational options for modern learners.
  • Distance learners have the flexibility to take classes at any time of day or night that suits their schedule. They are not limited to times that classes are being offered on campus.
  • Online programs can often be completed on a part-time basis, which allows adult learners to upgrade their education without having to take time away from work or family responsibilities.
  • The course material that online students complete is identical to what students work on in an on-campus program in many cases. They can receive an identical level of education without having to set foot on campus.
  • The diploma, degree or certificate issued once the work has been completed is identical to one obtained by a student who attended classes on campus.

Voice Tracker Array Microphones Effectively Record Lectures For Online Students

Online students need the freedom to log into their course website and access materials at a time that they find convenient. Classroom microphones must be powerful enough to pick up the instructor’s speech clearly so that every word can be conveyed clearly to these distance learners.

Acoustic Magic’s Voice Tracker array microphone provides high-quality sound for classroom recordings. It can be used with both conventional and VoIP conferencing systems.

If the off-site student participates in the class through a loudspeaker in the classroom, acoustic echo cancellation (AEC) becomes an important requirement. Acoustic echo occurs when the voice of the far end students from the loudspeakers in the classroom is picked up by the open microphone in the classroom and sent back to the far end students as an echo.

If the Voice Tracker array microphone is connected to a conventional conferencing system that has its own AEC, the Voice Tracker I can be used. If it is connected to a VoIP conferencing system that does not have a robust AEC, the Voice Tracker II should be used because it has a built-in AEC.

The sound quality is clear and reliable, and students will be able to follow the material being presented with ease.

When the quality of distance learning depends on the microphone used to record lectures, there is no better choice than the Voice Tracker!

How Speech Recognition Turns Sound Into Words & How We Give You Greater Freedom

Have you ever used a speech recognition microphone and wondered how what you are dictating gets translated and turned into words on the screen? Find out now and see how our Voice Tracker speech recognition microphone gives you greater freedom!

How A Speech Recognition Microphone Turns Sound Into Words

The process involves several important steps, including:

Converting Sound To Digital Data

When you speak, you are creating vibrations in the air. Once the voice recognition microphone picks up the sound, an analog to digital converter translates the analog wave into digital data, which is the only language the system understands.

In order to do this, the microphone digitizes the sound by taking measurements of the wave frequently. The system then filters the digitized sound to remove unwanted noise.

This process also adjusts the sound to a constant volume. Since people don’t always speak at the same rate of speed, the sound may need to be adjusted to match the speed of the sound stored in the template sound samples which are stored in the system’s memory.

Software Breaks Words Into Patterns

The signal is divided into small segments of consonant sounds, and the software matches them with elements in the language to put together meaningful expressions.

The final step is the most challenging: The software examines the words and compares them to ones in its dictionary to decide what it thinks the user has said and displays the best match on the screen. All of these processes are performed within a few seconds of the words being spoken into a microphone.

Speech Recognition With Greater Freedom

Our Voice Tracker array microphones are certified by and work great with Dragon NaturallySpeaking and other speech recognition software. The Voice Tracker is also certified at a greater range than other microphones. Normally, with most speech recognition software, your mouth has to be very close to the microphone, but with the sensitivity and quality of Voice Tracker™ Array Microphone, you can still get accuracy at a few feet away.

With the benefit of the Voice Tracker array microphone’s hands-free and headset-free capability, you can experience even greater freedom than other speech recognition microphones. This benefit can be a crucial advantage especially for those with disabilities such as quadriplegics.
