<TITLE>Am I using play_and_detect_speech correctly?</TITLE>

<!-- Converted from text/plain format -->
<P><FONT SIZE=2>Hello,<BR>
<BR>
I am using play_and_detect_speech with Java ESL in my IVR applications.<BR>
<BR>
Previously I call it again each time after I receive any recognition event,<BR>
like recognition complete, no-input-timeout, or recognition-timeout,<BR>
it seems to work fine.<BR>
<BR>
Now I have changed my app to issue play_and_detect_speech command based on<BR>
my available system utterances as well as the speech event.<BR>
<BR>
I.e., I use a separate thread to constantly check if there is a system utterance coming in<BR>
from another component of my application, if there is any utterance I issue the command which will<BR>
speak the new utterance and listen to user input no matter whether or not previous<BR>
command has finished. And if there is any speech event (recognition result, timeout etc.)<BR>
the play_and_detect_speech command is also issued but with playing silence.<BR>
<BR>
Obviously the new command will stop the utterance speaking of the previous command if it is not finished.<BR>
<BR>
My question is<BR>
<BR>
will the new play_and_detect_speech command also stop the previous ASR listening<BR>
or will there be many ASR listening channel and sending speech data (or silence) to ASR server?<BR>
<BR>
Do I need to explicitly issue a "stop" commnad before issuing a new play_and_detect_speech?<BR>
If yes, how to do that, by "detect_speech stop"?<BR>
<BR>
Recently there is a network traffice problem (lots of connections /data transportation to the ASR server machine)<BR>
when I am running my application. I am not sure if this is because of other issues<BR>
or because of my new changes to the way of using play_and_detect_speech.<BR>
<BR>
Please any one could shed a light on this?<BR>
<BR>
Many thanks!<BR>
<BR>
