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 audio signals on a plurality of channels and processing the audio signals on the channels to improve the signal-to-noise ratio thereof. The processed audio signals on each channel are then fed to associated voice activity detection algorithms and further processed. A voice or silence determination is then rendered based on at least the output of the voice activity detection algorithms. A voice activity detector is also provided.
