I don't know a ton about speed reading, but one tip I had heard was you slowly count to 10 over and over again (just barely whispered) as you're reading the words. It's hard at first, but you kind of get used to it. Once you can get the meaning of the words just by looking at them (rather than "saying them in your head" - which is impossible while youre counting aloud), you can scan them faster and faster.
The upper bound for how fast you can scan your eyes over words is much higher than the speed at which you can "say them".
