[Freeswitch-users] issues in simultaneous speech recognition and TTS via mod_unimrcp

[x.liu]

Hello,

I am trying to do simultaneous speech recognition and TTS via 
mod_unimrcp using detect_speech and speak.

What I want to achieve is to enable a user to say something like "shut 
up" to stop TTS rather than using standard barge-in to stop TTS.

When I spoke something during playing a sentence, I noticed there were 
some recognition results from FS log,
but my ESL app didn't get any DETECTED_SPEECH or BEGIN_SPEAKING events.

Has any body had similar experiences before?

 From Arsen Chaloyan's comments at 11 July 2011:

"If I'm not mistaken, neither Asterisk nor FreeSWITCH are currently
capable to play a TTS prompt while making a recognition. However, I
don't see any conceptual problem here. This is somewhat not
implemented yet for those open source projects. Other UniMRCP based
implementations do this job very well."

I am wondering if the current mod_unimrcp does not support concurrent 
recognition and tts
or if I am not using it properly?


Thanks!
