Developing speech recognition system in Matlab

Hello, I am trying to develop a speech recognition system using matlab.

I am able to record the voice and store it. I have used melcepst function from voicebox (www.ee.ic.ac.uk/hp/staff/dmb/voicebox/voicebox.html) toolbox. So, I get mfcc from this.

Now after this feature extraction, i wish to do feature matching using DTW or HMM? How is this possible?

 While testing the data user has to speak the same word . So, I wish to confirm the procedure
1) test voice is to be stored in a file 
2) then mfcc is to be used on this and 
3) using DTW or HMM both the mfcc of train and test data is matched.

Is this the correct way to go about? Kindly help. Thanks,

Nidhi
