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

[x.liu]

I can use play_and_detect_speech app and set Recognition-Mode=hotword to 
do the hotword barge-in.
This is working.

I am still trying detect_speech and speak for simultaneous speech 
recognition.
I can receive the events like DETECTED_SPEECH or BEGIN_SPEAKING if I 
speak after the TTS finishes
The problem is that I can not receive those events in my ESL client if I 
speak during the TTS is playing,
but I can see there are some recognition results from FS console.

Tried various things, didn't get it work.

Does anybody have any clue on this?

Thanks!
Xing
