dtw文件是运用DTW算法实现安静环境下语音识别的。其中vad.m是端点检测程序；lpc.m是计算LPC参数的程序；lpc21lpcc.m是计算LPCC参数的程序；mfcc.m是计算MFCC参数的程序；dtw.m是实现经典DTW算法的程序；dtw2.m是实现高效DTW算法的程序，testdtw.m是最终测试程序，其中可以通过改变其中的特征参数名选择不同的特征参数。-dtw file DTW algorithm is to use speech recognition in quiet environments. Which is the endpoint detection process vad.m　lpc.m is to calculate the LPC parameters of the program　lpc21lpcc.m procedure is to calculate the LPCC parameters　mfcc.m procedure is to calculate the MFCC parameters　dtw.m the classic DTW algorithm to achieve the program　dtw2.m DTW algorithm is to achieve efficient procedures, testdtw.m is the final test program, which can change the parameters in which different parameters were selected.
