[asterisk-speech-rec] SpeechBackround: accepting DTMF and speech atthe same time? Why?

[Stephen Keller]

I'm not sure exactly how SpeechBackground works -- one of the
Asterisk-experts can probably shed more light on that -- but the LV
Speech Engine supports DTMF grammars.

That certainly presents a workaround to your problem. Just load a voice
grammar and a DTMF grammar, and if the Engine detects DTMF input, it
will not parse it through the usual speech recognition, and you can get
the DTMF input back into your application.

Subject: [asterisk-speech-rec] SpeechBackround: accepting DTMF and
speech atthe same time? Why?

A number of my users have phones that beep when each number is pressed.
It appears that the SpeechBackground app is picking up this sound,
interpreting it as speech, and returning an invalid result.

Looking at the source it seems that the app looks for both DTMF and
speech in parallel?  Is this correct?  Is there a straightforward way to
to destroy the speech engine but continue to receive the DTMF input the
instant DTMF is detected?

Thanks
