Qt下使用微軟的TTS

Qt下使用微軟的TTS

下載下傳并安裝上圖勾選的兩個，建議按預設的路徑安裝

安裝完成後，接下來就是寫程式了

首先在建立的.pro檔案中添加

LIBS +=.\sapi.lib lib在下載下傳的檔案中可以看到，也可以在你安裝的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;

//擷取SpVoice接口

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

if (SUCCEEDED(hr))

pVoice->SetVolume((USHORT)100); //設定音量，範圍是 0 -100

pVoice->SetRate(0); //設定速度，範圍是 -10 - 10

hr = pVoice->Speak(L"你好", 0, NULL);

pVoice->Release();

pVoice = NULL;

//釋放com資源

::CoUninitialize();

基本的代碼就是這樣，一定要加上#include <window.h> 否則會出現bug

接下來是借用别人寫的類，直接調用即可

分别是speech.h 和speech.cpp檔案

#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       //用線程是為了防止一直按“speak”而導緻挂掉

Q_OBJECT

private:                //類為公共靜态類，類構造由類内部自己調用，是以可直接用私有構造

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); //設定音量，範圍是 0 -100

pSpVoice->SetRate(0); //設定速度，範圍是 -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();

調用該類後，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());

結果如圖所示

在文本框中輸入文本，點選speak按鈕便可有聲音發出

但該程式還是存在了問題，在初始化時，會出現如下的提醒，但不會影響使用，要是有大神知道解決辦法，歡迎留言評論。
