[asterisk-speech-rec] First attempt not working

Tue Oct 10 10:04:43 MST 2006

I am trying to use my new Asterisk/Lumenvox install for the first time.
I set up extension 6000 to ask "Please say yes or no", and based on the
response, I playback 'yes', 'no' or 'invalid'.  Unfortunately, it keeps
coming back as invalid.  The variable ${SPEECH(results)} keeps coming
back as "0".  

Following are the setup (yesno.gram, extensions.conf) and the results
(Asterisk CLI, and Lumenvox SRE log).  The only error is in the SRE_Log.

Any assistance would be appreciated.

Also, I've read about 'tuning' Lumenvox, but I don't see any utilities
to do that.

Thanks,
Adam
