You could provide an alternative text in pdf as well. I don't 
know if screen readers can pick it up, though.

\documentclass[12pt]{article}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}

\begin{document}
The Pythagorean Theorem is
\pdfliteral direct {%
   /Span << /ActualText (a\ squared\ plus b\ squared\ equals\ c\ 
squared) >> BDC
}%
$a^2+b^2=c^2$
\pdfliteral direct {%
   EMC
}
\end{document}
