im testing mod_pocketsphinx with the pizza demo, i followed instructions from

https://wiki.freeswitch.org/wiki/Mod_pocketsphinx

and i also copied the latest wsj1 and communication model to the grammar folder.

then after called 74992, i heard the voice prompt of "delivery or takeout" but fs seemed not responding to my speech,

nothing changed at the fs console while i say "takeout" or "delivery", the pastebin is at

http://pastebin.freeswitch.org/22513

so do i missed any configuration or grammar files? any hints are appreciated.
