[Freeswitch-users] Am I using play_and_detect_speech correctly?

[Liu, Xingkun]

Hello,

I am using play_and_detect_speech with Java ESL in my IVR applications.

Previously I call it again each time after I receive any recognition event, 
like recognition complete, no-input-timeout, or recognition-timeout,
it seems to work fine.

Now I have changed my app to issue play_and_detect_speech command based on
my available system utterances as well as the speech event.

I.e., I use a separate thread to constantly check if there is a system utterance coming in 
from another component of my application, if there is any utterance I issue the command which will
speak the new utterance and listen to user input no matter whether or not previous
command has finished. And if there is any speech event (recognition result, timeout etc.)
the play_and_detect_speech command is also issued but with playing silence.

Obviously the new command will stop the utterance speaking of the previous command if it is not finished.

My question is 

will the new play_and_detect_speech command also stop the previous ASR listening 
or will there be many ASR listening channel and sending speech data (or silence) to ASR server?

Do I need to explicitly issue a "stop" commnad before issuing a new play_and_detect_speech?
If yes, how to do that, by "detect_speech stop"?

Recently there is a network traffice problem (lots of connections /data transportation to the ASR server machine)
when I am running my application. I am not sure if this is because of other issues 
or because of my new changes to the way of using play_and_detect_speech.

Please any one could shed a light on this?

Many thanks!

Xing
