title: How to compare two MFCC feature vector or similarity between the MFCC feature vector of two speech utterances
body: <p>I have extracted 13 MFCC features of two utterances. Feature set for first utterance is of size 11*13 and other is 18*13.  So, how to compare two feature sets to find the similarity between these two words?</p>
  
  <p>I am not using any classifier, if someone know, which algorithm the standard tools follow for the comparison of MFCC feature vector. Please suggest me so that I can implement it. </p>
