More Accessibility in Ubuntu DVD?

[Cleverson]

Hello,

I'd like to know if there is in Ubuntu DVD a larger number of 
pre-configured accessibility features than in Desktop CD, namely some 
Screen Reader other than Orca and some Synthesiser.

I'm evaluating what's the best image for me to download. If the DVD 
environment doesn't differ from the CD, I'll download the CD and install 
aditional software from the Internet when I need it latter.

Thanks
Cleverson
