title: Applying K-means to MFCC Coefficients for ASR
body: <p>I have divided my audio signal into 20ms frame with 10ms overlap. As a result I have 500 frames. I have computed the MFCC coefficients for each frame. I want to do Vector Quantization for each frame using the K-MEAN algorithm.</p>
  
  <p>I have 16 MFCC Coefficients per frame (vector length: 16). Now K-MEAN Requires 2 Vectors to form the cluster diagram (one along X,one along Y), however I have only one vector (the 16 MFCC coefficients per frame).</p>
  
  <p>So how do I proceed? Do I take adjacent frames and apply K-mean to the adjacent frames?</p>
