I had applied for a loan and this company called me back with a sales voice agent. It was the 3rd time it spoke that I figured it was AI. It wasn't very good. It didn't stop when I spoke, which made me wonder if it was a human, and it kept starting every exchange with exactly the same speech cadence - which was the give away. Then I asked if it was AI and it hung up on me! If I didn't think the company was shady (I already did) before the call, hanging up when I asked if it was AI did it for me.
