Using MS speech sdk5.1 in QT for text reading

1. First, let's talk about your environment configuration. It doesn't make sure This Code applies to all configurations.

Operating System: Windows XP SP3

Compiling environment: QT sdk1.2.1 and msvc2008

Since Microsoft Speech SDK is used, you must first install it:

Http://www.microsoft.com/en-us/download/details.aspx? Id = 10121

Download the two images in the red box. After the download is complete, install speechsdk51.exeand then install speechsdk51langpack.exe,

Follow the default installation path and use the path in the code.

Because the sphelper. h header file is used in the code, errors may occur during compilation. For the solution, see the following link:

2. We encapsulate the call to the MS speech sdk5.1 API in the speech class, and then call the interface provided by the class to read the text.

The following describes how to implement the speech class. Let's talk about the code.

First, add the following code to the Pro file:

    INCLUDEPATH += -L"C:/Program Files/Microsoft Speech SDK 5.1/Include"    LIBS += -L"C:/Program Files/Microsoft Speech SDK 5.1/Lib/i386"

The following is the header file speechclass. h.

#ifndef SPEECHCLASS_H#define SPEECHCLASS_H#undef UNICODE#include <sapi.h>#include <sphelper.h>#include <comdef.h>#define UNICODE#include <windows.h>#include <windowsx.h>#include <commctrl.h>#include <QString>class speech{public:    speech();    ~speech();    void speak(QString text);    void setVolume(int volume);    void setRate(int rate);    void pause();    void resume();    void finish();    int  getVolume();    int  getRate();private:    void sounding(QString s, int voice);    void speak(QString s, int mode);    HRESULT                   hr;    CComPtr<ISpObjectToken>   pToken;    CComPtr<ISpVoice>         pVoice;    WCHAR *pChnToken;    WCHAR *pEngToken;    bool   over;};#endif // SPEECHCLASS_H

The following is the source file speechclass. cpp.

# Include "speechclass.

This speech class is used as a small example to illustrate how to use the speech class in QT.
