I was told this is possible via firmware update but TEXT to SPEECH would
be nice. I already have loads of audio-books in addition to the countless
reference materials and ebooks already collected so why not vocalize older
books or materials at will?
If a hardware chip is needed then I see no reason why the next version should
not include this option (besides reducing cost) The engine to drive the speech
module, I believe is mostly software as in Adobe Reader Pro.
