C++ sapi: User input, edit voice out -

#include <sapi.h> #include <string> #include <iostream>  //user inputs said// int main(int argc, char* argv[]) {     ispvoice * pvoice = null;      if (failed(::coinitialize(null)))         return false;      hresult hr = cocreateinstance(clsid_spvoice, null, clsctx_all, iid_ispvoice, (void **)&pvoice);     if (succeeded(hr))     {         std::wstring input;         while (true)         {             std::cout << "enter text:\n";             std::getline(std::wcin, input);              hr = pvoice->speak(input.c_str(), 0, null);         }     }     pvoice->release();     pvoice = null;     ::couninitialize();     return 0; } 

the code above allows user input want have spoken , works perfectly.

below msdn method of changing pitch , other similar action done same way.

hr = pvoice->speak(l"this sounds normal <pitch middle = '-10'/> pitch drops half way through", spf_is_xml, null ); 

i want change pitch, can't figure out how same action code have.

i know post 22-23 days old, decided take shot @ it. haven't been able voices @ disposal change pitch on fly, ms anna can.
