[Freeswitch-users] Am I using play_and_detect_speech correctly?

[x.liu]

Hi Chris,

Okay, thanks! I will have tries to see how it works.

For the normal use of the app: play_and_detect_speech, will it resume 
previous ASR session,
or will it stop previous session and restart a new session each time 
when I issue it via ESL?

For the app of detect_speech, I can first to start an ASR session by 
"detect_speech speechMod grammar grammarPath",
then I can do "detect_speech pause", or "detect_speech resume" or 
"detect_speech stop".
But for play_and_detect_speech, I am not sure how it works in terms of 
starting, pause, resume/restart sequence.

The play_and_detect_speech is a very good, useful app as it supports the 
barge-in. So we definitely need to use it.

Thanks!

Xing
