[asterisk-dev] Asterisk + MRCP for Speech Resources (TTS / ASR) ?

[Josh McAllister]

I'm curious if any standards are being followed with regard to
implementing Speech Recognition, and Text to Speech. MRCP seems to be
the prevailing standard for abstracting voice resources and I notice
that LumenVox, and Cepstral both support MRCP. 

Furthermore there is some work going on over at
http://www.speechforge.org/ to provide an OSS MRCP implementation called
Cairo. Cairo is currently capable of wrapping FreeTTS and Sphinx4. I
know a lot of work has already been done to integrate LumenVox, but I do
wonder what direction was taken, and if there is any possibility of
steering this way? 

Alternatively, would it be feasible to develop an * <-> MRCP plugin /
middleware using the existing Speech API? It seems like that might
bridge the gap for now, and really open the door for users to choose
from a variety of ASR software.

Side question -- I saw that Cepstral is now listed on Digium Partners
page, have I missed the announcement for integrated support, or is this
a hint of something to come? If this has not yet been implemented, has
any thought been given toward implementing via MRCP?

Thanks,
