You are correct that you need another language model.  On the Sphinx sourceforge 
page there is a perl script called SimpleLM that purports to take a list of 
phrases and create an LM, but the version I downloaded needed a lot of work to 
do it properly (lot of work == rewrite as ksh script/Python module).  That said, 
I was able to build a small corpus and have phrases not in the turtle command 
set be recognized.

One thing that I think might still be a stumbling block is the voice itself.  I 
happen to be fairly close to the speaker of the default model, so my utterances 
fall into the same frequencies, etc.  YMMV.

If you'd like, email me offlist and I'll send you what I have collected.
