I don't have an internal monologue at all (I am able to speak to myself in my head if I want to, but I seldom have a reason to). When I read, the information just gets uploaded to my brain. I don't vocalize words in any way, silently or otherwise. I don't read one word at a time either. When I read something quickly I can "feel" that my understanding of the material is lagging "the cursor", sometimes by even a paragraph at a time.
