If you're anauralic, what happens when you're reading and you hit a foreign word, or a word you don't know? Do you have to say it out loud, or can you "hear" the pronunciation in your mind by essentially speaking it sublingually? For me, I think my "inner voice" really is just sublingual speech wherein I don't move my lips, tongue or vocal chords. Although I can also "hear" the voices of other people I know if I think about them talking. (This would seem to be a requisite skill if you want to do impressions of people).

[edit: Maybe "sublingual" isn't the correct term for what I'm describing. I remember reading about some MRI experiments where they asked people to "talk" without making any sound, and this activated the speech parts of the brain as if they were using motor function to speak. But I can't recall the term used for doing this.]
