在C++Builder使用TTS(Text To Speech)

启动BCB，打开菜单项PROJECT->Import Type Library...,在弹出的对话框中单击Add,选择windows\speech目录下的Vtxtauto.tlb,加入VtxtAuto[Version 1.0]一项。单击OK，BCB就会自动生成一个VtxtAuto_TLB.cpp文件。这个文件包含了TTS引擎的COM类接口，可以用来与DLL文件通信。新建一个工程，将这个文件包含进来： 源码如下： //Unit.h #ifndef Unit1H #define Unit1H //--------------------------------------------------------------------------- #include <Classes.hpp> #include <Controls.hpp> #include <StdCtrls.hpp> #include <Forms.hpp> //--------------------------------------------------------------------------- class TForm1 : public TForm { __published:    // IDE-managed Components         TEdit *Edit1;         TButton *Button1;         void __fastcall FormCreate(TObject *Sender);         void __fastcall Button1Click(TObject *Sender); private:    // User declarations public:        // User declarations         __fastcall TForm1(TComponent* Owner); }; //--------------------------------------------------------------------------- extern PACKAGE TForm1 *Form1; //--------------------------------------------------------------------------- #endif //Unit.cpp //--------------------------------------------------------------------------- #include <vcl.h> #pragma hdrstop #include "Unit1.h" #include "wstring.h" #include "VTxtAuto_TLB.h" //--------------------------------------------------------------------------- #pragma package(smart_init) #pragma resource "*.dfm" TForm1 *Form1; IVTxtAuto *IVTxtAuto1; //--------------------------------------------------------------------------- __fastcall TForm1::TForm1(TComponent* Owner)         : TForm(Owner) { } //--------------------------------------------------------------------------- void __fastcall TForm1::FormCreate(TObject *Sender) {     WideString a = "Demo1";     WideString b = "Project1.exe";     WideString c= "Hi,I am trying to speak to you,Do you hear me?";     IVTxtAuto1 = NULL;     CoInitialize(NULL);     OleCheck(CoCreateInstance(CLSID_VTxtAuto_,0,CLSCTX_ALL,IID_IVTxtAuto, (LPVOID*)&IVTxtAuto1));     IVTxtAuto1->Register(a,b);     IVTxtAuto1->set_Enabled(1);     IVTxtAuto1->set_Speed(150);     IVTxtAuto1->Speak(c,vtxtsp_VERYHIGH); } //--------------------------------------------------------------------------- void __fastcall TForm1::Button1Click(TObject *Sender) {     if(IVTxtAuto1 != NULL)     {       IVTxtAuto1->Speak((WideString)Edit1->Text,vtxtsp_VERYHIGH);       ShowMessage("OK");//我的调试语句（没声卡）     }else{       ShowMessage("服务器没有初始化成功");     } } //--------------------------------------------------------------------------- //Project.cpp //--------------------------------------------------------------------------- #include <vcl.h> #pragma hdrstop USERES("Project1.res"); USEFORM("Unit1.cpp", Form1); USEUNIT("D:\Borland\CBuilder5\Imports\VTxtAuto_TLB.CPP"); //--------------------------------------------------------------------------- WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int) {         try         {                 Application->Initialize();                 Application->CreateForm(__classid(TForm1), &Form1);                 Application->Run();         }         catch (Exception &exception)         {                 Application->ShowException(&exception);         }         return 0; } //---------------------------------------------------------------------------
