My thoughts the following.  Reading aloud means translating
two-dimensional math into one-dimensional text.  This is exactly the
inverse of the problem of translating one-dimensional code into
two-dimensional math.  I strongly suspect that solutions to both of
these problems are correlated, and conversion of math to TeX
representation is the best choice.  Anecdotically many blind
professional mathematicians are very fine with spoken TeX

I would think that some slightly preprocessed TeX (e.g. with \cos read
as co-sain rather then backslash-si-oh-es) is the ideal.  In the first
version we can drop the preprocessing.

Good luck


The best thing about growing older is that it takes such a long time.
