I have got pocketsphinx 0.5 running on Windows Mobile 5.0. However, I'm getting only one 'hypothesis' no matter how long I speak into the PDA. Infact, I'm only getting the words -"THE", "SAY", "TURN" and "EIGHT" although I didn't mention any of these during the 'utterance_loop'.
BTW,
-I am using the code from continuous.c
- Sampling rate 16000
- HMM (wsj1) and LM (turtle) which come with version 0.5
I noticed that the number of recognised words in my PDA is way smaller than when I run in pocketsphinx_continuous.exe in cmd. Here is the output (if this is not too much info):

I have been debugging the code using my PDA for some time now and can't figure out why I am not getting good recognition. I need some one to advise how to proceed from here. I need to know what Sampling rate to use, do I need to create a new LM based on the PDA, why I'm I getting only one word printed out everytime?
Sorry for too many questions. I just wanted to bring everything to the table.
Many thanks

This certainly means your feature extraction is wrong. You need to review your changes and compare feature files with desktop version of the recognizer.
> I need to know what Sampling rate to use,
Most probably you need 8 kHz.

This forum is for sure not a good place to ask about pocketsphinx. David doesn't read it for example. Use #cmusphinx irc channel or mail to cmusphinx-sdmeet mailing list on sourceforge.
