Posted: Wed Oct 11, 2006 11:28 am Post subject: [asterisk-speech-rec] SpeechBackground Problem
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.

I am also finding that the entire SR process is very unreliable. It
gets the correct response only 20-30% of the time. Often I can scream
into the phone and it says it received no sound at all.
If I can't get this to work 99.9% with a simple yes/no, I'm probably
going to abandon this for now.

Adam,
The Speech Engine should be giving you much better accuracy and it
should be recognizing that speech occurred much more often. You may want
to play with the settings in lumenvox.conf.
One thing we would recommend is that you download the LumenVox Speech
Tuner. You will need a Windows machine to use it. Instructions on
downloading and installing it are available at
http://www.lumenvox.com/customers/help/LumenVoxTuner.htm. You will have
to point it at the License Server you have running (edit the
license_client.conf file in the Tuner installation directory). We
recommend you use the beta version of the Tuner, which is available on
the same FTP site linked to in the document above.
On your Asterisk box, make sure you have save_sound_files=yes in the
lumenvox.conf in order to save callsre log files for the Tuner to use
(the files are saved in /opt/lumenvox/engine_7.0/Lang/Responses/).

Increasing the core debug and verbose to 999 shows nothing additional.
Looping back to SpeechStart instead of SpeechBackground does nothing.
I am also finding that the entire SR process is very unreliable. It
