These links are from Dottuta (Kuwait Univ) of the Webheads, based on work with a blind student. The voice potential of the Web (and for Deaf students, the visual/closed captioning potential) should really make a difference. I have added some annotation to the list of sites, which are mainly British and American. The most promising of these is first on the list. I'd love to hear from anyone with information about sites in other languages, or additional English language sites.
Camera Obscura has lists of links to a wide variety of text-to-audio friendly sites, including hypertext archives, museums, query-submission forms for search engines, news readers, government resources, etc. Relatively conveniently organized by type of resource.
WWW Resources and Homepages [for the Blind] - a list of useful links, unfortunately in no particular order, but with helpful descriptions.
The Braille Institute's page of links (alpha-sorted) to various non-profit organizations that assist the blind, with a brief description of the mission of each. It would take some initiative to further explore and sort through the links on each of these pages.
Action for Blind People, according to this site, "is an expert national (UK) organisation, ensuring blind and partially sighted people receive practical support in all aspects of their lives." News and information relevant to issues affecting people with this disability, all with audio recordings. (Wouldn't a podcast feature to be nice?)
Tom Lorimer's Home Page, "has been set up to assist the Visually Impaired computer user locate information and services relating to blindness." The site is mainly focused on computer, software, and Internet issues and resources, but also has links to other useful sites. Useful links, though not well organized.
VIP Games Zone offers "accessible sound games for blinds [sics] and visually impaired people," and includes some free games and an e-list to converse with other players. Appears to be home-made software, but I haven't had a chance to try it out.
And this from Nergiz, also of the Webheads:
Odiogo claims to create text-to-speech podcasts for your blogs with a "Listen Button feature deployed in next to no time for WordPress, Blogger, TypePad, BlogEngine.NET and Terapad platforms."
And see the previous entry also [yeah, here's where I need a wiki instead!]
By the way, this blog also has an audio text-to-speech feature, though it usually takes a few days for the audio to be compiled and linked to my posts.
