I want to use MFCC (Mel-frequency cepstral coefficients) and DTW (dynamic time warping) algorithms to make a speech comparison script. I calculated MFCC and got 13 coefficients for each frame.
How do I calculate DWT from that? Should I discard the frames and just look at coefficents as an array. I read in this post: Speech recognition using MFCC and DTW(Dynamic Time Warping)? that you should calculate DTW between each frame, but I don't understand what I should do after I have calculated all those DTWs. If I have one audio sequence of $n$ frames and the other one of $m$ frames, then I get $n \times m$ DTW costs. And, where do I go from there.
