[Freeswitch-users] FreeSwitch - PcoketSphinx Prompt Playback & Recognition Issue...

[Moiz Chinoy]

Hi,

I have downloaded and build the Freeswitch from
http://files.freeswitch.org/freeswitch-1.0.3RC1.tar.gz on Windows XP.

Everything built successfully. 
Then I configured PocketSphinx as described at
http://wiki.freeswitch.org/wiki/Mod_pocketsphinx.
The problem is that prompts (wave files) are not being played properly while
testing the Pizza demo i.e it plays, stops then start playing again...

I am using heaset for testing.

Moreover, the recognition seems to be very poor.

Any clue what might be the issue?
