It's easy to train yourself to do that though. Just find your favorite audiobook and listen to it daily. First listen to it at 1.5x, then adjust to 2x after a few days, then 2.5x after a few more days etc. You'd be surprised how fast your brain can actually process the information.

Personally when I did this I feel irritated when I speak because my sped-up audiobooks have conditioned me into thinking I should be speaking at that rate, but it's just not possible for my mouth and tongue to move that fast physically.
