Abstract :
The speech direction finder described here is a relatively simple device based on an off the shelf microcomputer. It can provide the direction to a talker to within 3 degrees of azimuth angle on a single spoken syllable, will only respond to speech, and when used with Wallace linear array microphones can provide this at distances of 50 feet or more. There are numerous applications for the device which may enhance the quality of audio and video teleconferences.
