通过使用matlab自带的小波函数对语音信号进行处理，首先对载入的语音信号snow.wav添加高斯白噪声，然后对加噪的语音信号进行三层小波分解，最后分别采用强制性和默认阈值两种方法对信号进行消噪处理，强制性消噪方法直接将分解的高频系数全部变为0，默认阈值通过对分解的高频系数设定阈值来进行消噪-By using MATLAB built-in wavelet function of speech signal processing, first on the loading of the spee

matlab语音工具箱，用于实现matlab处理语音信号的各种工具，分析语音信号的matlab内置函数-Voice toolbox in matlab, is implemented by a variety of tools matlab voice signal processing, matlab built-in function analysis of speech signal

用MATLAB对一语音信号进行小波分解，分别用强阈值，软阈值，默认阈植进行消噪处理。-Using MATLAB to a voice signal wavelet decomposition, respectively intensity threshold, soft threshold, default threshold denoising processing plant.
