Alex text-to-speech voice: absolutely stunning
My favorite part is that Alex actually breathes audibly just before starting a new sentence! I couldn't figure out why it sounded so natural, then a friend pointed out the quick inhalation just before he reads each new sentence. Unreal!
It's not perfect: he makes more pronunciation mistakes than Cepstral David, but that's to be expected for v.1.0. I hope Apple will add a "Corrections" feature to the Speech preference pane to allow people to enter corrections, new words, and exceptions.
But it's still a home run for people who use text-to-speech!
