Abstract

A visual information directed microphone array system is presented in this paper. This system uses a real-time mouth tracking system to direct a beam-former focusing on the mouth. The microphone array system is implemented on a PC with a Signalogic 8-channel DSP board and reports a better signal-to-noise ratio sound capturing in a high noise environment.
