One thing that helps my reading, paradoxically, is listening to speech on headphones whilst out on a walk. I sometimes find myself visualising the words as I hear them. Presumably this helps me to recognise them more speedily in print.
One key technique in beginning speed reading is to stop subvocalizing the words, so that you can go faster than speech.
You can read faster if can see the wordand think the concept rather than mentally sounding it out:
abcdefghijklmnopqrstuvwxyz
alphabetically
You can also see groups of words at a time:
The end of the road
