Sorry I was not clear on this. _Mathematica's option is *clumsy*. _ I agree that some grouping markers are necessary. Example.
Let s = a*(b + c) + d SpokenString[s] is
a times the quantity b plus c plus d (which Mathematica 9 pronounces defectively as ahtimes ...., and fails to group the b+c.)
SpokenString[s, IncludeParentheses -> True] is
a times open parenthesis b plus c close parenthesis plus d
which is, in my opinion, CLUMSY. Incidentally, the documentation is buggy. It directs you to type "IncludeParentheses"-> True, but the quote marks are unnecessary. Perhaps this is all the work of a summer intern.).
How then to group the expression if not to say o-pen pa-ren-thi-sis (6 syllables) and close pa-ren-thi-sis (5 syllables)?
How about A times open b plus c close plus d or A times quantity b plus c endquantity plus d A times left b plus c right plus d
