[Freeswitch-users] pocketsphinx and event socket

Mon Mar 2 16:49:09 PST 2009

 I think you need to talk to Brian. 

Apparently this is a "new" pocketsphinx which works on a different format from those found in the pizza demo. 

Also, pocketsphinx crashes if it "hears" anything outside the grammar which apparently is a longstanding bug. Brian mentioned they are working on getting this fixed. 

I kept getting:

2009-02-25
19:49:32 [ERR] mod_pocketsphinx.c:140 pocketsphinx_asr_load_grammar()
Can't open dictionary
C:\Source\freeswitch-snapshot\Debug\grammar\default.dic.
2009-02-25 19:49:32 [WARNING] mod_pocketsphinx.c:219 pocketsphinx_asr_close() Port Closed.

The suggestion was to "Just copy the cmudict.0.6d to
default.dic, not sure how well it will perform on windows.. if it does
badly you can slim the dictionary down to words you know you'll be
using."

https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/cmudict/cmudict.0.6d

That gave me more problems so I'm waiting for the fix.

Mark.

Thanks Addison.

The Pizza files are there (as mentionned is it a copy of an already

working system).

In fact freeswitch is complaning about

/usr/local/freeswitch/grammar/model/communicator which he cannot load

So somehow freeswitch is not willing to open the files, but I have no

clue why. So any hints are welcome.

Best regards

Peter
