语音识别系统源程序

基于matla的语音识别系统附语音文件，采用动态时间规整算法（DTW）。

function NormMatrix = CMN（Matrix）



[rc]=size（Matrix）;
NormMatrix=zeros（rc）;
for i=1:c
    MatMean=mean（Matrix（:i））;  %Derives mean for each column i in utterance
    NormMatrix（:i）=Matrix（:i）-MatMean; %Subtracts mean from each element in
                                         %column i
end
