Forging Voice
LyreBird is a system that can accurately reproduce the voice of someone, given a large amount of sample inputs. It’s pretty good—listen to the demo here—and will only get better over time.
The applications for recorded-voice forgeries are obvious, but I think the larger security risk will be real-time forgery. Imagine the social engineering implications of an attacker on the telephone being able to impersonate someone the victim knows.
I don’t think we’re ready for this. We use people’s voices to authenticate them all the time, in all sorts of different ways.
EDITED TO ADD (5/11): This is from 2003 on the topic.

“Voice photoshopping” has been around for some time. Use that search term and you’ll find many a reference to Adobe’s closed source audio solution which is considerably better than this one.
