Abstract:
A video conferencing system has a microphone array that operates to receive acoustic signals corresponding to voice activity and to determine that the signals are either from within a sound field of interest and from outside the sound field of interest, and if the signals are from outside the sound field of interest the system attenuates these signals by not steering a microphone array beam towards these signals.
