The Voice Tracker Array Microphone was the original implementation of our patented, automatically and electronically steering, "listening beam" technology. It has an analog audio output at mic level, and is powered by a wall power converter so there is no risk of loss of performance as batteries run out. More info @

Speech Recognition: Since the Voice Tracker operates differently from other types of microphones or audio input devices, you should retrain your speech recognition software. Be sure to select USB Array Microphone during the “New User” setup. Personalized vocabulary can usually be transferred to the retrained “User”.

Troubleshooting: Acoustic echo cancellation. If the ref signal is too strong or too weak, AEC will not work well. Make sure the playback level in the PC is set to midscale. Turn up the volume on the (external) speaker itself if more loudness is desired.

No Audio: Check whether the LEDs track the talker. If not, reboot (repower). If so, the problem is probably in the computer setup. Make sure it is looking for recording input where the Voice Tracker is connected (USB, Mic in, or Line in).

Analog or USB Audio too strong.

Make sure the output level switch is set to mic level

Analog or USB Audio too weak.

Make sure the output switch is set to line level
