METHOD FOR IMPROVING NEAR-END VOICE ACTIVITY DETECTION IN TALKER LOCALIZATION SYSTEM UTILIZING BEAMFORMING TECHNOLOGY

摘要

A method for detecting voice activity comprises receiving audiosignals on a plurality of channels and processing the audio signals on thechannels toimprove the signal-to-noise ratio thereof. The processed audio signals on eachchannel are then fed to associated voice activity detection algorithms andfurtherprocessed. A voice or silence determination is then rendered based on at leasttheoutput of the voice activity detection algorithms. A voice activity detectoris alsoprovided.
