I am not a blind but I would much prefer hearing latex formula word by word than whatever alternative they came up with(e.g "a slash pm b" or "slash frac a b").

I am not a blind but I would much prefer hearing latex formula word by word than whatever alternative they came up with(e.g "a slash pm b" or "slash frac a b"). I really doubt you can unambiguously say long formulas lot more succinctly. Even after having looked at the formula, I can't follow a lecture without having to look at the board and that is human translation which would be better than MathML.
