I was calling cleaning services and just had my first AI voice call. It was eerie. I didn’t notice it was AI until maybe 20 seconds in. It sounded very real. The AI even stutters, makes mistakes, or says “um” like a real person would. But there was something off about the perfectly consistent vocal inflections and it said “okay” the exact same, very curt way after each of my responses. I’m guessing in 5 years I won’t be able to tell if I’m talking to a person or AI.
