Good point.  There is no way that a screen reader could make these
distinctions from inspection of the printed output.  It would have to work
directly with the source file.

I genuinely cannot see how a screen-reader, given only a formatted page
image with no semantic markup, can possibly know that the "2"
in x^2 + y+2 = z^2 should be pronounced "squared" whilst the "3" in this
footnote^3 should be pronounced "see footnote 3" and the "-1" in this
trigonometry (sin^-1) should be moved to the front of the "sin"(e) and
pronounced "arc" !
