Some suggested applications for the Voice Tracker:

Meeting and lecture recording:

Because the Voice Tracker can pickup at very long range while suppressing background noise, with a 360° field of view, it's best application in terms of units sold is meeting recording, lecture capture, and courtroom recording.

Lecture capture is the most appealing since more than 360 schools use the Voice Tracker, and many are large quantity users (have bought more than 100). The Voice Tracker is recommended by most of the lecture capture such as Tegrity, Echo 360 and Panopto. See the attached sales guide to understand the several benefits the Voice Tracker offers in this application.

Courtroom and deposition recording is another good application.The Voice Tracker I is usually preferred for meeting/lecture recording because of its longer pickup range, easy ceiling mount, and lower price. The Voice Tracker II is chosen if the user wants portability, or wants to use the microphone for additional applications like distance learning or conferencing.


The attributes that make the Voice Tracker I a good choice for meeting recording make it ideal for conferencing as long as it is connected to a system that has acoustic echo cancellation (Polycom, LifeSize, etc).

Automatic Speech Recognition:

Some people can't or don't want to use headsets or handheld microphones for automatic speech recognition. Consequently, we have sold quite a few Voice Trackers to doctors, lawyers and handicapped users.

Home automation

This has been a small application, but is growing. The long pickup range of the Voice Tracker facilitates command-and-control throughout an entire room.
