title: word timestamps in python pocketsphinx
body: <p>I'm using pocketsphinx python bindings on ubuntu 11.10. I pass it a grammar and an audio file and it works perfectly. I am now looking to find the timestamp of each word in the audio file. I have seen:</p>
  
  <pre><code>void ps_seg_frames(ps_seg_t *seg, int *out_sf, int *out_ef);
  </code></pre>
  
  <p>which I believe should do what I need. 
  However I can't seem to find away to do this in python.
  Is this possible?</p>
