Ops.. I wrote this in a hurry so I made a little mistake.

ASTER converts Latex to Audio. So you might want MathML to Latex/Tex and not
Latex/Tex to MathML.
See http://www.cse.ohio-state.edu/~gurari/docs/mml-00/xhm2latex.html or
http://tilman.de/mathparser/anleitung_en.html for instance.

Cheers,

Helder
