I agree.
I, myself, stumbled into the accessibility arena because I could not
obtain accessible CFA/FRM certification study materials, though it was
probably a blessing in disguise.

I think access to STEM materials (and we are talking STEM content
here, even if the format is not that of STEM instructional material
per se) is a huge problem and prevents millions of people with
disabilities from pursuing exciting, innovative and profitable
careers.
Having dabbled in math accessibility as well, I can attest to the fact
that A.T. vendors generally do not treat math/STEM accessibility it as
a high priority, because so few users request it.
The reason so few users do that is that many are discouraged and never
try to pursue a STEM degree/career, so we have a classic chicken and
egg problem (which I wish we could turn into a bacon and egg problem).
Partially I am still pinning my hopes on increased adoption of the
MathML standard for pure math, but you are right in that document
authors really need a way to tell screen readers what content should
be read, leaving it entirely to the user and the user default setting
is a dangerous game.
I know CSS3 has some sort of speech control, but I do not claim nearly
sufficient expertese to understand that, or to what degree it is
applicable (though it is on my wishlist of topics to master in 2014,
along with a lot of other things). PDF/Word/other formats require
their own standards, and screen readers need to converge on a standard
as well, and the whole interface needs to be supported by authoring
applications, rendering apps, possibly the O.S. as well as the screen
reader, not to mention that the TTS used by the user may have its own
pronounciation rules which can override the screen reader default. so
we are facing a gigantic mess of standards and technologies, and STEM
definitely pushes the limit.
I am hoping ePub3 along with MathML may start pushing the envelope in
this area, but I honestly am at aloss as to seeing the big picture of
how this could realistically be achieved.
My initial answer was supposed to be limited in scope to how this
particular problem could be addressed for this particular situation,,
but it is hard not to turn it into a long rant about how important it
is that we fix the bigger picture I admit. Reading your post was
refreshing and I found myself grinning inanely and even saying the
words "heck yeah" out loud.
If you have some ideas and info or relevant links on how to address
the bigger picture, feel free to contact me on or off-list with links
to such. I am always curious to keep abreast of the latest and
greatest in document accessibility.
All that being said, I have to be careful not to stray too far into
how to fix the world discussion on this list, so I will stop here.
*grin*
Happy ew year everyone!
