I think that is "reading with a headache." I don't think my comprehension would ever catch up because if I miss a word it throws the whole thing off and I don't know what I'm reading. Also, with quotes and citations and so on it's just annoying, as sometimes you like to actually check the footnote at the bottom of the page.
Further still, I still "hear" the word in my mind no matter how fast it goes, or, until it becomes a blur.
"Advocates of speed reading generally claim that subvocalization "places extra burden on the cognitive resources, thus, slowing the reading down." These claims are currently backed only by controversial, sometimes non-existent scientific research; in some cases, concepts are drawn from pseudoscience and urban myths about the brain. Speedreading courses often prescribe lengthy practices to eliminate subvocalizing when reading. Normal reading instructors often simply apply remedial teaching to a reader who subvocalizes to the degree that they make visible movements on the lips, jaw, or throat.[2]
It may be impossible to totally eliminate subvocalization because people learn to read by associating the sight of words with their spoken sounds. Sound associations for words are indelibly imprinted on the nervous system—even of deaf people, since they will have associated the word with the mechanism for causing the sound or a sign in a particular sign language. Subvocalizing is an inherent part of reading and understanding a word, and micro-muscle tests suggest that subvocalizing is impossible to eliminate. Attempting to stop subvocalizing is potentially harmful to comprehension, learning, and memory. At the more powerful reading rates (100-300 words per minute), subvocalizing can be used to improve comprehension.
