音听测试证明了这一点。-New algorithm for speech compression noise, a noise reduction of speech based vad method. This new algorithm derived from vad technology and spectral subtraction, it firstly deal with the noise signal vad, then the masking threshold is based on perception of spectral subtraction to reduce noise, increase access to clear signals. Compared with other algorithms, the better, speech test proves this point.
