speech recognition

1．[x1, x2] = vad(wavefile)

　　----detect the beginning and the end of a speech signal.

2．ccc = mfcc(wavefile)

　　----calculate the Mel-scaled Cepstrum Coefficients.

3．[dist] = dtw(sourcefile, testfile)

　　----matching the source speech file and the test speech file by using the Dynamic Time Warping algorithm.
