Anyone know how many hours of training data it takes to build up a convincing model of someone’s voice? It was 10’s of hours when I did a bit of research a year ago… the article says social media is the likely source of training data for these scams, but that seems unlikely at this point.

I don't remember the exact number but I did see an article recently that said it was videos on social media like you surmised.

And it was a pretty minimal amount of data needed. Definitely not tens of hours. Less than one hour iirc.

Is it safe to assume that if you don't have any family that posts videos to Facebook/socials you are in a safer place?

Make sure to use a fake accent when talking to strangers on the phone

I certainly am hoping so myself.

The technology has clearly come a long way in a short time, really fascinating.

I remember the first examples I read about being trained with celebrity read audiobooks because they needed so much audio data. I want to say Tom Hanks or Anthony Hopkins but I could have that confused with something else.

TorToiSe can work off of just three ten second clips when you're using a pre-trained model. No telling if that'll sound any good.

I’ll have to check that out, thanks for the link.

The most advanced Model I know just needs half an hour of your voice or sth.

Someone else mentioned that Microsoft has one capable of working with far less material.

But 30 minutes is definitely short enough to make this sort of scam/attack feasible in my mind.
