Description: MFCC,即倒谱系数，也是语音的一个特征之一，能够充分利用人耳的特性
％ 具体的求法就是预处理，然后加窗，进行傅立叶变换，再求出功率普
％ 然后得出其自然对数，最后进行dct变换
％ 代码是用matlab写的，用到的一个语音工具箱，可以从网络上下载。-MFCC, that is, just a few pedigree, as well as a voice of one, to take full advantage of people's ears% of the specific characteristics of the solution is pretreatment, then increasing the window, Fourier transform, another sought power pu% then come to its natural logarithm, culminating transform% Extra code is written in Matlab. use of a voice box can be downloaded from the Internet.
