Abstract
The present invention relates to the field of voice activity detection technologies, and more particularly, to a voice activity detection method. The method comprises: providing an acquisition unit for acquiring an external sound signal; providing a judgment unit for judging whether the sound signal is a voice signal; if the sound signal is a voice signal, starting a voice processing unit for processing the sound signal; if the sound signal is not a voice signal, the voice processing unit is kept in a sleep state. With the voice activity detection method, the voice processing unit with large power consumption is made to be in a sleep state for a long time, and therefore, the entire system can be kept in a low-power consumption state; the voice activity detection method is low in implementation cost and can obtain better performance with a small amount of calculation and less resource consumption.
