METHOD,DEVICE AND CODER FOR VOICE ACTIVITY DETECTION

摘要

A method, a device and a coder for voice activity detection are provided. The method for voice activity detection includes: obtaining the fluctuating characteristic values for representing the fluctuating value of the background noise, when the input signal is the background noise (101); self-adaptively adjusting the parameters related to the judgment criterion of voice activity detection VAD according to the fluctuating characteristic values (102); VAD judging the input signal using the self-adaptively adjusted parameters related to the judgment criterion (103).
