title: How to choose pocketSphinx's language model in python
body: <p>I just need a speech recognition library in linux. Then I choose CMU Sphinx, and use pocketSphinx with python.  I test that <a href="http://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/pocketsphinx/scripts/livedemo.py" rel="nofollow">demo</a>. This example runs well in my computer with poor accuracy.</p>

  <p>I know that I need a language model, and I have downloaded it. So, How to set my pocketSphinx use that 'lm'. I mean, How to fix that demo file to use that language model. (and acoustic model.)</p>
