Researchers warn 'humans cannot reliably detect' audio deepfakes even when trained

Senior correspondent Alicia Acuna reports the latest from Denver. AI-generated audio that mimics humans can be so convincing that people can't tell the difference a quarter of the time – even when they're trained to identify faked voices, a new study claims. Researchers at University College London investigated how accurately humans can differentiate between AI-generated audio and organic audio, according to a report in the science and medical journal Plos One. The study comes amid the rise of deepfakes, videos and pictures that can be edited to appear as if they are actual images of other people. "Previous literature has highlighted deepfakes as one of the biggest security threats arising from progress in artificial intelligence due to their potential for misuse," researchers wrote in their paper published this month.
