Grammars can only be *either* speech or DTMF. You'll need to pass multiple grammars to Nuance.

Christopher, thanks for your reply,

I tried to do it in several ways but couldn't make it work - either I got an error from Nuance or no results when entering a dtmf.

Can you please send me an example of such grammar?

Thanks

Best regards

I think your MRCP server should also be able to do the DTMF detection if you add it as a rule to the grammar.

Hello,

I'm trying to make use of Nuance ASR engine for speech recognition.

I succeed to make 'play_and_detect_speech' works in lua for speech only, but I
want the recognizer to detect also dtmf that the user might enter.

I did some "googling" but could not understand if there is a way to use
multiple grammars. I found a clue saying this:

"I need to update the wiki... it got out of sync last year when luke-jr added
support for multiple grammars per session.

Chris"

Found in here -

I also saw a C++ example to load grammars before calling the detect and
thought maybe that can work but didn't find anything like it for lua.

So my question - is that possible (and of course how...)?


Thanks a lot for your help
