[Freeswitch-users] Not recognizing voice in mod_pocketsphinx

Mon Jan 30 21:01:46 MSK 2012

I am picking up this old thread as I have exactly the same problem and 
my log looks just the same.

I am using mod_pocketsphing through event socket with a new freeswitch 
built from GIT. I also tested the Pizza demo with no success. The server 
is a Ubuntu 10_04.

The module is loaded successfully:
2012-01-30 17:26:08.776531 [CONSOLE] switch_loadable_module.c:1299 
Successfully Loaded [mod_pocketsphinx]
2012-01-30 17:26:08.776531 [NOTICE] switch_loadable_module.c:363 Adding 
ASR interface 'pocketsphinx'

However it does neither detect speech via event socket nor in the pizza 
demo. And I cannot see any DETECTED_SPEECH events via event socket.

In the logs I see the following:
2012-01-30 18:52:26.536529 [DEBUG] switch_ivr_play_say.c:1678 done 
playing file /usr/local/freeswitch/sounds/en/us/callie/pizza/GP-Greeting.wav

pizza_order  undefined)

playing file 
/usr/local/freeswitch/sounds/en/us/callie/pizza/GP-DeliveryorTakeout.wav
EXECUTE sofia/internal/200 at my.domain detect_speech(resume)

So there is no error message.

Googling around I expected I should see something like this:
SpeechTools.jm:150 console_log() ----XML: <interpretation 
grammar="pizza_order" score="44"> <result name="match">TAKEOUT</result> 
<input>TAKEOUT</input> </interpretation>

But there is none of this type in the logs.

What could I do to investigate further?

    * maybe there is an older version of pocketsphinx on the system,
      which conflicts? (system was set up in may 2011)
    * Is there a way to have more debugging informations within pocket
      sphinx?

Any help is appreciated.

Best regards
Peter
