It's a metaphor, but only just. I talk to myself in my head, but only at the end of a thought process once I've formed some ideas and I'm trying to crystallise them into an argument that sounds right. Like others have said here, if you switch to thinking in English too early on you cripple yourself -- it's just too slow and linear for dealing with multiple threads, relationships and associations, which our minds are brilliant at.

Like you suggested, I also think in spoken words when I'm questioning myself, playing devil's advocate. "Why does that matter?" "Is such and such really the case? Prove it." "You're ignoring some really important factor over here."

I find thinking AND trying to record stuff frustrating. If I'm dictating to a recorder I'll always speak in fragments of sentences, or talk ridiculously fast if I'm on a train of thought, because I can feel the next three or four links & associations coming, and I'm scared of losing them while I finish the one I'm currently talking about. Of course, being scared of losing them pretty much guarantees that you do.

Regarding the "inner voice", I find it's always self-directed. I can keep thinking, but choose to talk or not talk in my head. I suppose, if ever you get words in your head that aren't self-directed, pay very close attention.
