[Freeswitch-users] How to implement TTS barge-in using FS ESL

[xl127]

Hi,

The first problem I need to solve is that FS stucks when I speak during 
the prompt is playing.
It looks like the recognizer is not listening any more. It works fine if 
I speak after the playing prompt finishes.

I tried Nuance and PocketSphinx recognizers and got same problem.

Any idea about what the possible causes are?

Thanks!
Xing
