Probably it' easier because phone calls aren't high quality.
It's pretty trash, but it's not completely horrible. It's also over a year old, so the SOTA is likely better today.
This is a global issue. For examples, please look into the societal concerns surrounding 'deep fakes', and 'fake news' for answers to your first two questions.
I don't believe the concerns about deep fakes and fake news. I think they're no worse than what we've always had. Those fears are exaggerated by arrogant hand-wringers who somehow assume their own beliefs are exempt from manipulation and it's only intellectually inferior "other" people who are susceptible. They're so fixated on the popular political ideas that they forget they should be on a crusade against religion which is the elephant in the room when it comes to people being misled.
Synthetic is scalable.
I wouldn’t call the voices unconvincing. They used to have a better demo though where it would impersonate celebrities like Trump. It was very interesting to demo it.
I believe the contrary: that high-quality, convincing audio (and video) deepfakes will be cataclysmic for society. Voice audio is one of the last digital artifacts that people will believe with their senses.
When Donald Trump’s “grab them by the p—“ audioclip came out, he was at least forced to acknowledge it.
Once high-quality audio deepfake tools become available, amateurs will be able to flood the web with fake audioclips of politicians saying things they never did, and truly unscrupulous politicians will be given technological cover for any damning audioclips of theirs that get leaked.
Once we cannot trust our senses, then we will be only able to trust our institutions and then our tribes. But trust in institutions is already decaying rapidly, so in the end there only ideological tribes will be left.
there is a difference in scale and effect between every idiot in the world can fake as many impersonations of people that they want (and they can coordinate this impersonation with 100s of others who have a goal with this impersonation) and Rich Little calling up somebody's granny and claiming to be Jimmy Stewart.
Audio deepfakes, when they finally arrive for real, will simply reduce the effort required for voice impersonation. They do not make possible new feats of impersonation that were never possible before. They can still have an effect on society for sure, but I believe the concern is out of proportion with the effect.
