[GoogleCodeExporter]

Please provide any additional information below.

Ok, everything seems to work fine, I'm just not getting the returned recognized 
speech.  It's even recording the utterances into the data directory which tells 
me everythings working. 

Here is what asterisk shows:  (notice it's missing the translation)

I get an NLSML error instead of getting my utterenance response....

Also, in unimrcp server, it's missing anything of the type 
application/x-nlsml...

Here's an excerpt of the server from wheere it should be:

So, it appears to do everything but return the utterance, probably something 
simple.  


It amazes me how complicated it is to get this stuff working.  I've done many 
years of development with asterisk, but, never anything like this.

Okay, if I use the Communicator_semi_40.cd_semi_6000 dialog files instead of 
hub4_wsj_sc_3s_8k I get a response, but, it's always wrong.

So, better question, which files do I put into data/communicator ??? 

Thanks,

I personally haven't used the PocketSphinx plugin for a while, and cannot be of 
any help here at this time.
