Once, I answered the phone for a business and read off the required introductory spiel. When I didn't get a response, I read the spiel again. The caller responded, "Oh, I'm sorry. Your voice is so well modulated, I thought it was a recording."
In one sense, that's a compliment; the caller thought I sounded professional. By the same token, it could also mean I sounded robotic and soulless.
I imagine this has happened to a lot of radio announcers.
