Depends on what I'm doing. It's usually one voice, but if I'm trying to think through something or if my ADHD is turned up, I get what I call "the committee." For thinking through something, different perspectives all chime in, and I like to imagine it like some kind of round table debate. I "talk" with myself through ideas, and sometimes I change my mind about what I do because ultimately I know the most sensible talking point is the right one.

If my ADHD is behind it, though, then it's more like a room full of people all pointing out different things at the same time. One's complaining that the noise outside is too loud. Another's distracted by the birds out the window. Another voice is debating what I should eat next (even if I'm not hungry.) Yet another is trying to remember the lyrics to a random song. Then the "responsible adult" of the group is trying to get everyone else to STFU and focus on the task at hand.

I find that caffeine goes a long way in getting the committee to chill and listen to each other. It's not too surprising that stimulants get them all in line, but it's still interesting to experience.
