How does one read that quickly with any degree of comprehension, particularly with regard to technical books?
I am a fairly intelligent person, with a large vocabulary, but forcing my "mind's voice" to read faster than a normal conversational pace dramatically reduces both enjoyment and retention of material. Doubly so for anything of technical content.
I believe the enabler to fast reading is to skip verbalization totally - i.e., not a "minds voice" that is speaking quickly, but going from seeing a sentence to getting the concept of that sentence without vocalizing, without ever having had a representation of how that sentence sounds, bypassing the hearing/speech centers of your brain, reading on an abstract purely visual level.
I feel a mental voice when reading e.g. poetry or when writing a draft for a presentation/speech, but all other content is purely visual. I tend to recall the visual location where a fact was written, e.g. that was on the right side of some page around the bottom part, but not how it sounded.
