Not that I did any real research here, but I found these links after struggling with the Microsoft Narrator installed on my PC. (Some of these are links to links...)
I've used Narrator, which isn't as bad as it is just plain unfriendly to a new user. Also, Narrator doesn't play nice with all documents. I spent more time trying to de-glitch it than I did listening to my stuff. So...
In the voice of Bill Engvall, "Heeeere's your links!"
- Techovity shares some links I'm checking out.
- Browsealoud
- ReadSpeaker
- Wikipedia's list of free & commercial readers.
Not a lot of links, but I'll be scouting for more as I have time.
