I asked if anyone could point me to examples of "how fast do screenreaders
actually read", a few months ago.[1] The best examples I could find at the
time, are here:
and here

Searching a few days ago, I learned that the average speed that experienced
users generally use is 250-400 wpm, and that the default settings are
around 180wpm.
(Note: Users seem to typically talk about the speed they use in terms of x%
of maximum, rather than wpm, e.g. "I've got 63% with rate boost, and
rising.  I used to think 75% with JAWS was fast, but not anymore.  I'm just
turning it 1% faster every couple days, and I'm doing it because I can."

https://en.wikipedia.org/wiki/Words_per_minute#Speech_and_listening says
English language audio books are generally at 140-160 wpm.

I believe this is partially through the long-term efforts of: our
developers who have an understanding of accessibility issues, and our few
blind editors and many sight-impaired editors who give regular feedback and
bugreports.[3] Immense kudos to all of them.

(Sidenote:  I compiled a list of all the related pages I could find, at
Anyone's additions to that listing, or notes/improvements/merge-efforts at
the linked pages over the longterm, would be greatly appreciated. :)
