We are currently testing our in-house implementation of MRCP on Asterisk and have successfully integrated with Nuance Speech Rec and TTS. I am currently cleaning up the code and will hopefully release soon to the Asterisk community.

Hi,
We have an MRCP connector to Asterisk based on Unimrcp as specified by Renato. We have tested it with Nuance ASR and TTS (both V1 and V2). You can find more info at http://www.voip-info.org/wiki/view/Asterisk+cmd+MRCPSpeech .
Thanks.

Hi thereDoes anybody have any experience using
Nuance speech recognition from Asterisk?
It seems that all the documentation I
come across discusses Lumenvox/Asterisk integration, but
not a word
about Nuance.
I've created a nuance.conf file and
added a line defining where my Nuance server can be found,
but I
doubt the file is ever read.
I do not seem to be able to get past
the SpeechCreate command in the dialplan.
I've tried SpeechCreate and
SpeechCreate(nuance), but the ERROR variable is always 1
afterwards.
I've had a look at the source code, but
I'm still puzzled.
The find_engine function should return
the default engine if no arguments are passed, and search
through the list of engines if an argument is passed.
I have not been able to find out
- how to add engines to Asterisk,
- how to see the list of available
engines (if any) or
- where the default engine is defined.

This would be correct. A module has to be written that uses
the engine in question. No module
is in the tree for Nuance, so it won't work.

Adding an engine to Asterisk requires writing an interface
module using the speech recognition
API in Asterisk. It acts as the glue between the way
Asterisk does speech recognition and the way
the speech solution (such as Nuance) does. Without this you
can't use it. The API is defined in the
speech.h header file in include/asterisk

Could you use MRCP?

There is currently no MRCP module in the tree either. It
may exist outside in the world somewhere
but I have not seen it.

That project is based in the UniMRCP (http://www.unimrcp.org) which is a
great C project that provides a good abstraction to server
integrators
and client developers.
