%X Voice activity detected(VAD)is a very important step for speech signals processing,a new method of the VAD was proposed based on the selected sub-bands vector distance.It calculates the summation of power spectrum in very frame as characteristic vector.For detecting the voice activity,the method calculates the characteristic vector distances between frames to acquire the distance track.Theoretical analysis and experimentation show that compared with entropy-based algorithm and cepstrum-based algorithm this ...
