PocketSphinx Plugin Available

[Arsen Chaloyan]

I would like to announce the availability of PocketSphinx ASR plugin for UniMRCP server.

PocketSphinx UniMRCP server can be used with an MRCP compliant client, which supports JSGF grammar.
Currently supported ASR features are as follows:

Methods:

• DEFINE-GRAMMAR
  
• RECOGNIZE
  
• GET-RESULT
  
• START-INPUT-TIMERS
  
• STOP

Events:

• START-OF-INPUT
  
• RECOGNITION-COMPLETE

Headers:

• Noinput-Timeout
  
• Recognition-Timeout
  
• Completion-Cause
  
• Completion-Reason
  
• Save-Waveform

Grammar: JSGF

For the instructions on how to build and configure PocketSphinx with UniMRCP refer to
http://code.google.com/p/unimrcp/wiki/PocketSphinxPlugin

Please note, everything is working now, nevertheless this is basic availability only.
I have mostly tested the integrated solution in the following setup
SipPhone -> FreeSWITCH/UniMRCPClient -> UniMRCPServer/PocketSphinx

However it requires further testing in different environments from different speakers, e.t.c.
In other words, your feedback is welcome.

Thanks,
