pocketsphinx: LM change before the 2nd pass

[lococuad]

Hi,

I am a newbie and I get lost easily diving into the code of pocketsphinx.

I understand that pocketsphinx does 3 passes (fwdtree, fwdflat and bestpath).
The 1st pass (fwdtree) is performed during the execution of ps_process_raw ().
The 2nd pass is performed during the execution of ps_end_utt () inside the
function ngram_search_finish (). I want to change the language model just
before starting the fwdflat search. May you help me with the steps for this
change? ; can I keep in memory several LMs and activate the adequate one
during runtime in order to save the LM loading time?

Thanks in advance.

You can just call ngram_model_set_select before starting flat search.

It's questionable why do you need to change one trigram model to another but I
suppose you understand that already.

Thanks a lot. I've been busy these past few days and I couldn't try your
suggestion until now.
