Please, does WINE latest development version contain SAPI 4 or SAPi5 build in support? Or I must install MIcrosoft speech SDK? I AM wondering, how complex would be for you to develop SAPi4 or SAPi5 functions from scratch, so their names and returned values would be same like from Microsoft, but code will be yours. Because Wine is in fact complex emulator, which try to do its best to emulate API functions from Microsoft but code is yours. Because development of speech engine from scratch is not easy.
