I am writing a matlab code that would be able to read the audio file and then compare it to the another audio and recognize if those audio are the voice of the same person. In both type of the audio, would have the same word utterance and the audio is about 1 minutes long. I have come to know that the approach of sliding windows using hamming window would work best on this approach but have a very little idea on this. The simple code to read an audio file and then display a portion of 10s is as below :

[x,fs, nbits]= wavread('01-AudioTrack 01.wav');
subplot(211)
plot(x)
title('Entire Wave') 
smallRange = 1:100000;
subplot(212)
plot(smallRange,x(smallRange))

How do I make Hamming window each of 10ms in this case and what approaches should I take to deal with this problem ?
