Description: MFCC (Mel Frequent Cepstral Coefficient) in M-File.
epresentation of the short-term power spectrum of a sound, based on a linear cosine transform of a log power spectrum on a nonlinear mel scale of frequency.
MFCCs derived as follows:
1. Take the Fourier transform of (a windowed excerpt of) a signal.
2. Map the powers of the spectrum obtained above onto the mel scale, using triangular overlapping windows.
3. Take the logs of the powers at each of the mel frequencies.
4. Take the discrete cosine transform of the list of mel log powers, as if it were a signal.
5. The MFCCs are the amplitudes of the resulting spectrum.

Description: 用matlab仿真0到9十个数字的语音识别
1、对语音的WAV文件和LAB文件进行处理,产生十个文件,每个文件对应于一个数字,存贮着该数字的波形文件。(shujuzhengli.m)
2、分别利用上面十个文件训练出十个HMM模板,具体方法是:首先将语音的波形文件分帧,以128个点为一帧,帧移为64,每一帧通过mfcc.m计算出13个系数,随着波形的长度不同,一个语音文件可以计算得到13*N个系数,截取13*15的矩阵(mfcc系数)用作训练数据。一般一个HMM模板用20组mfcc系数训练,得到初始状态分布、状态转移矩阵、高斯正态分布的均值和方差以及混合矩阵,这就是该语音的特征,存贮下来,识别的时候使用。(trainmfcc.m)
3、识别过程:识别的前面部分与训练相似,都是要计算得到mfcc系数,不同在于,识别时,将计算得到的mfcc 参数分别代入训练得到的HMM模板求出概率,比较出最大概率者,则该模板对应的数字就是识别的数字。(shibiesb.m)
4、用大量语音文件做测试,结果正确率为90 以上。-Speech Recogonition: Mumber 0-9
