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.
