If you stop trying to vocalise the words in your head you can really break away from the the time limit and just fly through text.
This is what I do when I’m reading academic papers for writing reports to see if the content is what I need.

I just use my teeth and it horrifys anyone I’m with…
Jokes on them though, because I’m the one with an open beer.
