Has Any1 Tried Responisve Voice?

[Chime Hart]

Hi All: In trying to look for something somewhat better than Voxin for my 
laptop, I got to hear a demo of a wonderful sounding voince from
www.responsivevoice.org
While I don't see a word "linux" anywhere on their page, I wonder how easy it 
would be to enjoy these voices with Speakup?
This is a developer working with Chime. I'm looking at using the javascript 
package mentioned above in concert with a node JS app that would act as a 
softsynth in his debian install. I'm just looking for information on how speakup 
sends information to the existing hardware synthesizers, so, I can write an 
adapter or mock some hardware and call the softsynth.
Back again live-and-thanks so much in advance for any guidance
