微软的sdk下载地址为：www.microsoft.com/en-us/download/details.aspx?id=10121

下载并安装上图勾选的两个，建议按默认的路径安装

安装完成后，接下来就是写程序了

首先在新建的.pro文件中添加

LIBS +=.\sapi.lib lib在下载的文件中可以看到，也可以在你安装的SpeechSDK中找到

LIBS +=-lole32

#include <windows.h>

#include <mmsystem.h>

#include <conio.h>

#include <iostream>

#include "sapi.h"

#include "sphelper.h"

using namespace std;

#pragma comment(lib,"winmm.lib")

ISpVoice *pVoice=NULL;

MainWindow::MainWindow(QWidget *parent) :

    QMainWindow(parent),

    ui(new Ui::MainWindow)

    ui->setupUi(this);

    //初始化COM接口

   if (FAILED(::CoInitialize(NULL)))

        return;

    //获取SpVoice接口

    HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void**)&pVoice);

    if (SUCCEEDED(hr))

        pVoice->SetVolume((USHORT)100); //设置音量，范围是 0 -100

        pVoice->SetRate(0); //设置速度，范围是 -10 - 10

        hr = pVoice->Speak(L"你好", 0, NULL);

        pVoice->Release();

        pVoice = NULL;

    //释放com资源

    ::CoUninitialize();

基本的代码就是这样，一定要加上#include <window.h> 否则会出现bug

接下来是借用别人写的类，直接调用即可

分别是speech.h 和speech.cpp文件

#ifndef SPEECH_H

#define SPEECH_H

#include <QThread>

#include <windows.h>

#include <windows.h>

#include <mmsystem.h>

#include <conio.h>

#include <iostream>

#include "sapi.h"

#include "sphelper.h"

using namespace std;

class Speech : public QThread       //用线程是为了防止一直按“speak”而导致挂掉

    Q_OBJECT

private:                //类为公共静态类，类构造由类内部自己调用，因此可直接用私有构造

    explicit Speech(QObject *parent = 0);

    ~Speech();

public:

    static Speech * getInstance();

    void speak(const QString & speakText);

    void setSpeechEnabled(bool speechEnable);

private:

    static Speech * pSpeech;

    ISpVoice * pSpVoice;

    ISpObjectToken * pSpObjectToken;

    QList<QString> speechList;

    bool isSpeechEnabled;

protected:

    void run();

signals:

    void sendMsg(QString);

public slots:

};

#endif // SPEECH_H

#include "speech.h"

Speech * Speech::pSpeech = NULL;

Speech::Speech(QObject *parent) :

    QThread(parent)

    CoInitialize(NULL);

    pSpVoice = NULL;

    isSpeechEnabled = true;

    if(FAILED(CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_INPROC_SERVER, IID_ISpVoice, (void **)&pSpVoice)))

        return;

    else

        emit sendMsg("ERROR!! Can not create instance!!");

    pSpObjectToken = NULL;

    pSpVoice->SetVolume((USHORT)100); //设置音量，范围是 0 -100

    pSpVoice->SetRate(0); //设置速度，范围是 -10 - 10

  /* if(SUCCEEDED(

               SpFindBestToken(SPCAT_VOICES, L"language=405", NULL, &pSpObjectToken)))

        pSpVoice->SetVoice(pSpObjectToken);

        pSpVoice->SetRate(8);

    else

        emit sendMsg("ERROR!! Can not find token!!");

}*/

Speech * Speech::getInstance()

    if(!pSpeech)

        pSpeech = new Speech();

    return pSpeech;

void Speech::speak(const QString &speakText)

    if(!isSpeechEnabled)

        return;

    speechList.append(speakText);

    if(!isRunning())

        start();

void Speech::setSpeechEnabled(bool speechEnable)

    isSpeechEnabled = speechEnable;

void Speech::run()

    CoInitialize(NULL);

    while(!speechList.isEmpty())

        QString speakText = speechList.first();

        speechList.pop_front();

        wchar_t * pBuf = new wchar_t[speakText.length()+1];

        memset(pBuf, 0, sizeof(wchar_t)*(speakText.length()+1));

        speakText.toWCharArray(pBuf);

        pSpVoice->Speak(pBuf, SPF_DEFAULT, NULL);

        delete pBuf;

    CoUninitialize();

Speech::~Speech()

    pSpObjectToken->Release();

    CoUninitialize();

调用该类后，在MainWindows中直接用即可

MainWindow.h

#include "speech.h"

classSpeech;

Speech*speech;

MainWindow.cpp

speech=Speech::getInstance();

voidMainWindow::on_pushButton_clicked()

    speech->speak(ui->plainTextEdit->toPlainText());

结果如图所示

在文本框中输入文本，点击speak按钮便可有声音发出

但该程序还是存在了问题，在初始化时，会出现如下的提醒，但不会影响使用，要是有大神知道解决办法，欢迎留言评论。
