Accessibility

Accessibility is the topic of making computers more usable to those with disabilities, related to vision, hearing, and speech. Accessibility programs include text to speech, speech recognition, screen readers, and screen magnifiers. Efforts have been made by the leading desktop environments KDE and GNOME to try and make accessibility more accessible.

Accessibility programs are not just for the disabled or impaired. A lot of people have fun with text to speech, and could also enjoy the benefits of some accessibility programs, assuming accessibility programs like speech recognition and speech synthesis worked like people expect. As it stands, most of these complex speech accessibility projects seem bizarre and clumsy with most applications, to those who don't need to use them.
