People talk to themselves in 2 ways, by:
- vocalizing, which is the actual moving of your lips as you read, and
- subvocalizing, which is talking to yourself in your head as you silently
Both of these will slow you down to the point in which you find
that you can't read any faster than you can speak. Speech is a relatively slow
activity; for most, the average speed is about 250 WPM (words per minute).
Reading should be an activity which involves only the eyes and the brain.
Vocalization ties reading to actual speaking. Try to think of reading as if you
were looking at a landscape, a panorama of ideas, rather than looking at the
rocks at your feet.
