NPR: “Artificial intelligence has gotten so good at mimicking people’s physical looks and voices that it can be hard to tell if they’re real or fake. Roughly half of the respondents in two newly-released AI surveys — from Northeastern University and Voicebot.ai and Pindrop — said they couldn’t distinguish between synthetic and human-generated content. This has become a particular problem for celebrities, for whom trying to stay ahead of the AI bots has become a game of whack-a-mole.Now, new tools could make it easier for the public to detect these deepfakes — and more difficult for AI systems to create them. “Generative AI has become such an enabling technology that we think will change the world,” said Ning Zhang, assistant professor of computer science and engineering at Washington University in St. Louis. “However when it’s being misused, there has to be a way to build up a layer of defense.”
