Knoppix with a voice interface?

I am interested in a voice interface Knoppix edition that incorporates various open source accessibility technologies. I use Knoppix regularly but am a newbie to remastering. I have tried one edition for the blind but it only had a braille interface. Most blind or vision impaired people do not know braille. A Knoppix edition to demonstrate the power of open source solutions for accessibility could also be of use to average users and the illiterate. Any help or advise would be appreciated! Thank you. :)
Specific questions:
-Any recommedations for desktop environments that integrate with open source voice interfaces?
-Any recommendation of open source voice interfaces?
-Any recommendations for artificial intelligence interfaces?
-Any guidelines for minimal list of Knoppix files?

I don't know of any pacakges for voice recognition, but if you are looking for voice emulation, then you can try Festival.
