[Freeswitch-users] Am I using play_and_detect_speech correctly?

[Christopher Rienzo]

You are using that APP in a way that hasn't been tested.  Try to do
"speech_detect pause" and see if that helps.  It will reserve your ASR
session for reuse while "speech_detect stop" will tear it down completely.
 If that doesn't work, open a jira ticket and attach a full call trace.
 It's difficult to understand exactly what is happening from your
description.
