Yes. Mostly inside my head but out loud at times. I have a tendency to chide myself, and when I do, it comes out the way parents use a kid's full name when the kid is really in trouble. So I find myself saying something like, "Good job, Angelene ___ ___! You really f***** up this time!"
I don't know why; my parents didn't use my full name like that...
Also, I agree with TheOriginalMe about sentient beings. But I do talk to inanimate objects. Hell, I name certain inanimate objects like my car, computer, cell phone and so on. I believe lots of people talk to "themselves" and this thread backs me up.
