asterisk users - Oct 2009 - Asterisk and Nuance Vocalizer TTS Engine

Hi,
     How can I integrate Asterisk to Nuance TTS engine instead of Cepstral?
Has anybody done this? How is the architecture and can Java AGI be used to
communicate between them?

regards,
Vela Sivasankaran

According to asterisk-guru this has been done.  If you're just looking for
TTS and not voice recognition, this shouldn't be too problematic.

Hi,

I think you should use the nvcmdline utility to synthesize your prompt 
to a certain file to be specified. Afterwards, you could play that on 
your asterisk, for example a wav file. But this could be some kind of 
long lasting as the TTS synthesizes in realtime, i.e. the longer the 
prompt is the longer you have to wait for the file to play. So, using 
AGI should be worthwile to take a look at. Using the nvcmdline utility 
you should use bash AGI or something more scripty. If there is a Java 
API for Nuance Vocalizer (I do not know that) you also could use that.

Is this nvcmdline bundled with every Nuance TTS ?

I do not think so. Nuance Vocalizer follows RealSpeak (4.5) which based 
on some older products. I never have used RealSpeak on the command line, 
but I think the "standard" tool is what you should be looking for.
Some
years ago Nuance bought Rhetorical with their rVoice TTS. This had a 
command line utility named "tts-it" on board.
Hope this helps. Regards, Christophorus

I have made app_realspeak which integrates RealSpeak in Asterisk, so
it's usable from the dialplan or from AGI. It has been discussed a few
times on the list, eg in this thread:
http://lists.digium.com/pipermail/asterisk-users/2008-December/222734.html

Contact me if interested.
