the ones i own have speed control, but no pitch. they have a sapi5 and sapi4 version that come together in a package (in the ones i own)
i use pitch and speed controls in my "singing" programming. i love the natural voices, because they are ..well...natural sounding.
(i'm trying to not sound like a commercial) but i can't use them in my singing.
this frustrates me, but the voices are just-that good. i ended up using my att voice now.
