[asterisk-speech-rec] SpeechBackground Problem

[Adam Robins]

I've set up the following dialplan logic to test the Asterisk/Lumenvox
speech engine using a simple yes/no grammar.
If the SRE does not detect a valid 'yes' or 'no', I play a message and
then loop back to try again.  For some reason,
when I loop back to the SpeechBackground command after the first time
through, the audio from the "test-say-yes-or-no" 
file is not audible, although the CLI shows it playing.  Any ideas?
Thanks.
