Unlike 1st generation array microphones which have a fixed "listen" direction, the Acoustic Magic Voice TrackerTM Array Microphone automatically locates and electronically steers toward the talker. FREEDOM OF MOVEMENT
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 TrackerTM rapidly steers to the individual participants. HEADSET-LIKE PERFORMANCE
The Voice TrackerTM 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. WORKS AT LONG RANGE The Voice TrackerTM 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. EASY TO USE Our patented steering technology employs digital electronics and proprietary embedded algorithms. There are no moving parts, so the Voice TrackerTM 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. SUPPRESSES INTERFERING SOUNDS The Voice TrackerTM is also the only microphone to employ Location Dependent Squelch (LDSTM, 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. FEATURES Automatic electronic steering of "listening beam" to talker location
Selectable steering limits (60 degrees and 180 degrees) for speech recognition and teleconferencing modes
Selectable LDSTM to reduce annoying interference of additional talkers during speech recognition or feedback during teleconferencing
Two stage noise reduction (spatial filtering and noise reduction processing)
8 element, 18 inch long array for maximum range
5 element "in range" light to indicate location of chosen talker and sufficiency of signal
Microphone tilt capability to facilitate desktop or monitor top mounting
Weight: 2 pounds
Power: converter from 120V AC to 6V DC included The Acoustic Magic Voice Tracker ™ is a professional grade array microphone, which has been certified by Scan Soft for use with Dragon NaturallySpeaking. The Voice Tracker™ forms a listening beam (like a searchlight), which locates and electronically steers toward the talker. This spatial filtering reduces background noise, creating a very high signal-to-noise ratio, which results in low recognition errors, long range and fast response. It's 180 degree scanning range makes the Voice Tracker™ ideal for teleconferencing applications.
