[Asterisk-Users] Speech Recognition and Asterisk

[Mike Meyer]

All;

	Since I have interest in providing the capability for callers to speak
the department, person or number they wish to call, as well as other IVR
scenarios, I have been reviewing much of this lists email archives and
searching the web for open source voice recognition that will work with
the Asterisk PBX.

What I am trying to determine, is what will it take to get it working on
Asterisk? How much effort and cost?

	So far I have uncovered references to the following:

        1) VoiceXML standards, and forums
        2) OpenVXI - which supports VoiceXML, simulated speech,
        telephony
        3) PublicVoiceXML
        4) Sphinx - a Carnegie Mellon University Speech recognition
        project funded by DARPA
        
>From what I can tell, I feel I am uncovering the tip of the ice berg and
this may not be trivial. But it seems that the Voice recognition
application, once developed, would have to be linked via an AGI to the
asterisk dial plan.

Has anyone gotten Voice recognition working with Asterisk? Last I saw, a
few were attempting to apply Sphinx back in the December and April time
frame. Any shared successes, progress or direction on Sphinx or any
other VR app would be appreciated before I start down this road.

Thanks,
Mike Meyer
