Voice Tracker Array Microphone

The Acoustic Magic Voice Tracker Array Microphone is a scanning array microphone. It can capture talkers over a 180-degree field of view, at ranges of 20 feet or more. For VoIP telephony and conferencing, the Voice Tracker can be used with collaboration SW from Centra, WebEx and EDTLearning, etc. by participants spread out in a large conference room. The Voice Tracker has a mode that eliminates the far end acoustic echo that normally occurs with far field microphones, eliminating the need to use headset mics.

The Voice Tracker locates the talker, and electronically steers a "listening beam", like an acoustic searchlight, in that direction. This creates spatial filtering; sounds from other parts of the room are not picked up. The Voice Tracker also employs digital noise filtering algorithms to reduce stationary noise from fans, air conditioners, etc. This two-stage noise reduction, coupled with increased sensitivity since the Voice Tracker's eight microphone elements are utilized continuously and constructively, give the Voice Tracker range and sound quality.

Array microphone technology has also found application in speech recognition and voice control, as well as long-range recording.

For Speech Recognition, the Voice Tracker can be used with IBM's ViaVoice, ScanSoft Dragon Naturally Speaking, or Microsoft SAPI.

For meeting or deposition recording, the Voice Tracker can be used with PC based SW from WinScribe or FTR Gold, or handheld recorders from Sony or Olympus, to capture everything said in rooms at ranges of 20+ feet and fields of view of 180 degrees.

The Voice Tracker can be used to make recordings for later transcription when users want to have their hands free.
