Unlike 1st generation array microphones which have a fixed "listen" direction, the Acoustic Magic Voice Tracker Array Microphone automatically locates and electronically steers toward the talker.
For speech recognition applications like Dragon NaturallySpeaking, it is no longer necessary to sit rigidly in front of the microphone. The user is free to lean backwards, sideways, or even move around.
For speech recognition applications, it is no longer necessary to sit rigidly in front of the microphone. The user is free to lean backwards, sideways, or even move around. For teleconferencing applications, several talkers can take part since the Voice Tracker rapidly steers to the individual participants.
The Voice Tracker improves signal-to-noise ratios in two ways. First, its digital signal processor creates a listening beam (like a searchlight) that focuses on the talker and spatially filters noise from other directions. Second, its proprietary noise reduction algorithms filter out background noise and reverberations that are present in the acoustic environment.
The Voice Tracker contains the largest number of array elements available today, which, when combined with its two stage noise reduction algorithms, give it the longest effective range of any array microphone.
Our patented steering technology employs digital electronics and proprietary embedded algorithms. There are no moving parts, so the Voice Tracker is rugged, reliable, and easy to use. Simply plug it into your computer's sound card and a wall outlet. No software needs to be loaded, and there is no drain on your computer's processing capacity.
The Voice Tracker is also the only microphone to employ Location Dependent Squelch (LDS, Patent Pending) which de-sensitizes the microphone to sounds coming from pre-selected directions. Consequently, the array can reduce unwanted sounds coming from directions outside its field of view.
