I want to add

1) On tex4ht site

it is mentioned that certain files in ?texmf?/tex4ht/bin and
?texmf?/tex4ht/xttl (not sure where it is your distribution) will be
used for speak

2) In pdftex and in comp.text.tex was discussed example showing that
one can specify copy-paste buffer different from the "printed" text
(works only in AR or Acrobat AFAIK). There is a claim from Adobe that
it would be useful for accessibility features but it was not
explanation how


     You can easily write equations such as
     \pdfliteral direct {%
       /Span <<
        /ActualText ($ \esc sum_{i=1}^{n}i = \esc frac{1}{2}n \esc cdot (n+1) $)
     \pdfliteral direct {%
     in \LaTeX.
