METHOD AND APPARATUS FOR ADAPTIVELY DETECTING A VOICE ACTIVITY IN AN INPUT AUDIO SIGNAL |
摘要 |
The disclosure provides a method and an apparatus for adaptively detecting a voice activity in an input audio signal composed of frames. The method comprises the steps of: determining a noise characteristic of the input signal based on a received frame of the input audio signal; deriving a voice activity detection (VAD) parameter based on the noise characteristic of the input audio signal; and comparing the derived VAD parameter with a threshold value to provide a voice activity detection decision.
