说明：  语音噪声压缩新算法,一种基于vad的语音噪声抑制方法。这种新算法源于vad 技术及谱减法，它先对含噪声信号进 行vad处理，而后是基于感知掩蔽阈值的谱减法运算，降低噪声，获得清晰的增强信号。与其它算法相比，其效果更好，语 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.)
