|

Hello asterisk users!
Does asterisk (or any of its plugin) support MRCP to interface with 3rd
party professional TTS engine?
I've found very little information about this, for example:

ation
Thanks in advance!
Regards,
Claudio

Hello Olivier,
from what I've understood Asterisk (or its plugin) should act as MRCP
client.
I copy and paste from RFC 4463 (hope it doesn't brake through email
exchange):

As far as I see RTSP is needed to support MRCP.
But also concerning Asterisk and RTSP I've found little information
online:

and this old email:

Is there anything more?
Thanks,

I think such feature should rather come from VXML server but I may be
wrong.

| I agree with you as Asterisk's TTS or ASR plugins (Lumenvox ASR module for
instance, see http://www.lumenvox.com/products/speech_engine/), should
support MRCP but Asterisk itself don't need to.

I'm not aware of anything else.
In this case, RTSP is used to stream live video content.
I don't think MRCP is relevant for such usage : I see it targeted to scaling
TTS applications to a large number of simultaneous users.
Thanks,
Regards
