The bank thought it was talking to me; the AI-generated voice certainly sounded the same.

On Wednesday, I phoned my bank’s automated service line. To start, the bank asked me to say in my own words why I was calling. Rather than speak out loud, I clicked a file on my nearby laptop to play a sound clip: “check my balance,” my voice said. But this wasn't actually my voice. It was a synthetic clone I had made using readily available artificial intelligence technology.
