Mimicking a CEO's voice is wild. Makes me think of that story where a guy almost got scammed by a fake "relative" crying on the phone, but it was just a soundboard.
But what if that's the point? A good scam needs to feel real to work. If a soundboard can make someone panic and send money, then it's doing its job perfectly. The tech is just a tool, and the real trick is playing on people's fears.
