Optelec now offers a new video magnifier to persons with visual and auditory disabilities that also can read aloud printed documents (newspapers, books, business contracts, etc.). It's called the Optelec ClearView+ Speech and according to the company's website:
The ClearView+ Speech combines video magnification and accurate text-to-speech that makes it easy to select what you want to read. It allows you to enlarge materials to a more comfortable size or change the high contrast viewing modes with one master dial. To activate the Speech feature, just simply touch the screen and instantly enjoy listening to articles, letters and books with a natural sounding voice and full page overview.
The system runs about $3900, but it looks like it's worth the price. More details, including a video of the ClearView+ in action, can be found here.
