Yes that's the one, I forgot what it was called. Always found this part interesting (from the wiki):
"This inner speech is characterized by minuscule movements in the larynx and other muscles involved in the articulation of speech. Most of these movements are undetectable (without the aid of machines) by the person who is reading."
Try gently pressing your finger against your larynx when you read in your head - you'll likely find you read faster - this works for me, although I tend not to bother.
The worst thing about the inner voice is it's not just when reading, it won't be quiet at bed time. And I have a tendency to complete thoughts as words. Even if I know where it is leading, and what the conclusion is, it feels like I have to see it through and phrase it correctly in my head. I feel very uncomfortable leaving it hanging.
Exactly. Sometimes I even feel compelled to complete the sentence more than once (as if I wasn't paying attention enough the first time, so I feel the need to say it again). I think there is a subtle difference between that and "reading without production" (when I try it, it feels more like skimming text; I have to really try to pay attention). To me, reading/inner-speaking feels like engaging with the text; to only be able to "see" words would be lifeless (I'm assuming that some/many/most people can do both).
