Christopher Breen writes: "Leopard’s VoiceOver will support Grade 2 contracted Braille devices. Such devices include displays that communicate through a silicone ribbon or pad that changes shape to mimic traditional braille characters as well as note-takers, devices that include special braille keyboards. Plug one of these Grade 2 devices into the USB port of a Mac running Leopard, and it should work out of the box, allowing both braille input and output. The “Wow” feature for most users will be the inclusion of Apple’s new Alex voice, a synthesized English voice that sounds far more natural than what Apple has offered previously."
