Acoustic Magic Voice Tracker Microphone (AMVTM)

Acoustic Magic Voice Tracker Microphone The Acoustic Magic Voice Tracker microphone is a desktop microphone array suitable for speech recognition. Traditional desktop microphones do not work well with speech recognition as they pick up a lot of background noise such as the computer's cooling fans. The Voice Tracker is different because it has an array of 8 microphones that electronically steer a "listening beam" (like an acoustic searchlight) in the direction of the person speaking.

The microphone is approved by Nuance for use with Dragon NaturallySpeaking and by IBM for ViaVoice and works great with Ultra Hal Assistant. For more details on this microphone please check out the PDF Voice Tracker Array Brochure (255Kb).
