aloha, lisa!

thank you for providing the other half of the equation -- i have a few 
self-voicing apps specifically designed for persons with cognative, 
learning, or lanugage disabilities listed on the

http://esw.w3.org/topic/HTML/UAs

in particular:

Penfriend XL: http://www.penfriend.biz/
and ReadPlease: http://www.readplease.com/

any other applications that fit your real world user scenarios, please let
me know, so they can be added to the HTML WG wiki in order to reinforce the 
point that speech isn't just for blind/VI users, but has a multiplicity of 
very important use cases, such as charles chen's CLiCkSpeak

http://clickspeak.clcworld.net/

which, in the words of its developer:

quote
Unlike FireVox, which is designed for visually impaired users, CLiCK, Speak is designed for sighted user who want or need text-to-speech functionality. [...] If you're a sighted user who wants to have web pages read to you because you have cognitive issues (for example, dyslexia), because you have literacy issues (like me - I can understand spoken Mandarin Chinese just fine, but reading is difficult for me), because you want to reduce eyestrain and listen to a web page being read, etc., then you are likely to prefer CLiCk, Speak over Fire Vox." 
unquote

thank you lisa for keeping an important user group whose lives are tangibly 
affected by supplemental speech on the HTML WG's radar,

gregory.
