这是我自己改进的语音信号处理里面的，基于谱减法的语音处理，不仅适合初学者研究还适合有一定基础的研究者使用！-This is my own voice signal processing to improve inside, based on spectral subtraction for speech processing, not only for beginners study also have some foundation for researchers to use!

基于端点检测的谱减法语音增强，语音的去噪算法仿真程序，可以进一步改进-Endpoint detection of the spectral subtraction based speech enhancement

程序主要是在原有谱减算法的基础上通过调整改进增益的系数a，b来实现谱减的改进，改进的谱减法实现了很好的语音降噪效果。-In the original program is mainly based on spectral subtraction algorithm improved by adjusting the gain of the coefficients a, b to achieve improved spectral subtraction, improved spectral s

基本谱减法和改进谱减法对比，文本显示matlab图形(The comparison between basic spectral subtraction method and improved spectral subtraction method, there are 2 texts in the files to display the MATLAB graphics.)
