If I understand this correctly, they trained it to mimic a specific person, not just a human voice. That's... kind of terrifying. Trained to my voice, and given the right text, you could probably get me fired, possibly divorced, and maybe jailed. Trained to mimic Trump's voice, and given the right text, you might be able to start a war.
I imagine it's going to have a big impact when it first gets rolled out to mimic someone on the political stage, and then people will use it to discount any audio or video they don't like.
I consider that to also be a big impact. If recorded events are now only hearsay, it's going to be a lot harder to prove what actually happened - both in politics and in court.
Wow, this is impressive. Thank you for sharing! If that made its way on Hacker News on its own already, it surely deserved it.
For those who didn't go to the link, there's a short video demonstrating the technology -- one example shown is a YouTube video of George W. Bush being modified real-time by a webcam stream reenacting the facial expressions of the source user superimposed over the target.
