If you’re listening to or have already listened to the beginning of this episode, you probably noticed that the voice introducing Kimberly Adams sounded a bit off, right? That’s because it’s an audio “deepfake,” and it was created by Yisroel Mirsky at the Offensive AI Research Lab through a process called voice cloning. It uses software to study a short sample of someone’s voice and create a deepfake, which in this case took only 15 seconds to generate, according to Mirsky. It’s far from a perfect replica, but it turns out that scammers recently started to use deepfake audio for phone scams and in some cases have even succeeded. Marketplace’s Kimberly Adams spoke with Kyle Alspach, a cybersecurity reporter with Protocol, about how the tech behind audio deepfakes works and how they’re being used in phone scams.
