However, it is entirely possible to read at a much greater speed, with much better reading comprehension, through silencing this inner voice. The solution is simple - absorb reading material faster than that inner voice can keep up.
In the real world, this is achieved through methods like reading passages using a finger to point your way. You read through a page of text by following your finger line by line at a speed faster than you can normally read. This works because the eye is very good at tracking movement. Even if at this point full reading comprehension is lost, it's exactly this method of training that will allow you to read faster.
With the aid of software like Spreeder, it's much easier to achieve this same result with much less effort. Load a passage of text (like this one), and the software will pace through the text at a predefined speed that you can adjust as your reading comprehension increases.
