Although the right menu entry "Speak Expression" allows MathPlayer to be
self-voicing, the interface we have for screen readers is simply to return
the string of text to be spoken.  At the moment, MathPlayer is tied to the
IE environment, but if there was sufficient demand, a non-IE specific
interface/dll could be delivered.

They are separate, although MathPlayer can use prosidy to improve the speech
if you use a SAPI 5 voice.  We are also working on support for SAPI 4

MathML is a great intermediate form.  You might be interested in
and the paper

where they are using MathML as the intermediate language for various
(two-way) math braille code translations.
