Having listened to some of the demos, it's hard to imagine how this will sound. But a veteran radio reporter who lost the ability to speak is going back on the air next week using some voice simulation technology that "listened" to his previous reports and uses his old voice to make new stories.

Really amazing, although listening to the technology, it still leaves something to be desired. (You can try it at this link by typing a sentence or two in the box at the top of the page, choosing a voice and hitting play.)
