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 On 02/13/2013 03:44 PM, x.liu wrote:
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!
