Acoustic Magic Voice Tracker Conference Microphone

The Voice Tracker™ I Array Microphone was designed with two objectives. The first was to provide coverage throughout a large room for recording or conferencing applications to eliminate the need for multiple microphone/mixer setups, which require expert installation and are expensive. The second was to provide high quality audio for automatic speech recognition without the encumbrance of wearing a head set mic or holding a handheld mic.

Pick up over an entire room is accomplished in two ways. First, sensitivity was increased compared to conventional microphones by constructively adding the output of eight separate always on microphone elements. Second, spatial filtering and background noise reduction are used to eliminate sound from all areas in the room except that space around the active talker, so the increased sensitivity is not corrupted by noise.

As a consequence, the Voice Tracker™ I Array Microphone can pick up talkers at ranges of 30+ feet in meeting/classroom recording or conventional conferencing applications. It can work effectively for command control automatic speech recognition application at the same distances, and full vocabulary ASR at ranges of a few feet.

Scanning “Listening Beam”

Unlike conventional microphones, or first generation array microphones, which have a fixed "listen" direction, Acoustic Magic Voice Tracker™ Array Microphones automatically locates the active talker and electronically steers a “listening beam” in that direction. It can steer its “listening beam” over a 360 degree range, creating a wide field of view. For Meeting Recording or Lecture Capture or Conferencing Applications, the Voice Tracker™ Array Microphone captures all the participants since its “listening beam” moves from one talker to the next in milliseconds. 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.



Spatial Filtering for Noise Reduction

The Voice Tracker™ Array Microphone 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.

Ideal For :

Meeting & Conference Recording
Capturing talkers throughout a large room is a challenging task since sounds from other people in the room, as well as background noise, often obscure the speech. Usually, several microphones (with associated mixers) are required. The Voice Tracker™ Legal Array Microphone, with scanning unidirectional technology, enables full room coverage with a single microphone. This makes a lawyer's job easier when trying to obtain a quality deposition recording.

Audio and Video Legal Conferencing
The same attributes that make the Voice Tracker™ Legal Array Microphone, ideal for meeting recording make it an ideal microphone for audio and video legal conferencing. It can be used as an auxiliary microphone with expensive conventional conferencing systems, or it can be the main microphone for the coming, desktop based VoIP-based conferencing systems.

Certified Automatic Speech Recognition for Legal Dictation
As ASR engines improve, dictation using legal vocabularies from Dragon, iListen, Via Voice and others, is becoming more widespread. Many lawyers find it impractical to wear a headset or hold a handheld mic.
The Voice Tracker™ Legal Array Microphone is so sensitive, and its sound quality is so good, that it provides headset/handheld mic accuracy at ranges of several feet, enabling headset like accuracy without the encumbrance of wearing a headset.
The Voice Tracker™ Legal Array Microphone has been certified by Dragon NaturallySpeaking, ViaVoice, and iListen
