title: How to apply MFCC Coefficients to DTW
body: <p>I am trying to implement a Speech Recognition module using  Mel
  Frequency Cepstral Coefficient (MFCC) and Dynamic Time Warping (DTW).</p>
  
  <p>I divide the signal(x(n)) into frames with of 25ms with overlap of 10ms and find the MFCC parameters for each frame.
  My main doubt is how do i perform DTW in this scenario.
  Suppose there are M frames, and N(13) MFCC coefficients.</p>
  
  <p>So I have a M x N matrix.
  Now how am I supposed to compute DTW?</p>
