这个是有关于语音识别的的书籍，上面有很多基本原理和MATLAB的例子-This is a reference book for automatic speech recognition with matlab codes.

this file has codes that describes how to ccmpute the signal spectrum , the power spectrum, how to calculate the autocorrelation sequence of a signal, how to calculate the autoregressive coeffecients of a signal,and how to reduce the noisy elements i

声音识别中的分帧、加窗、mel滤波器的设计及滤波功能-in the field of speech recognition，these codes could make it come true that enframing and hamming.Also, it involves the designs of mel filter.

基于HMM的语音识别小程序，matlab代码-HMM-based speech recognition applet, matlab codes
