Did you really mean to ask: Is there any mathematical output that can
be read by a screen reader?

No, fonts will make no difference.
Screen readers tend to do just that: they read a screen just like a
person, making guesses about which symbol strings are words and ... .

Not much use without also telling her (human or software) thatnthere
is a Pythagoras theorem and etc etc etc ... ie they neeed a maths
course to read maths. Current screen readers have had an introductory
course in US English, they are reasonably pathetic at amything more

Mmmm, no comment!
