Introduction

Parts of this code are based on James Matthews' original article Visemes: Representing Mouth Positions.

Figure 1: GUI of application program

This project shows I can convert from Text into Speech that followed by mouth motion. Before you build this project, I suggest you to read my article , "Simple Program for Text to Speech Using SAPI". These steps for building project:

1. New Application

2. Setting SAPI on project

3. Building GUI of project

4. Coding

5. Testing

1. New Application

Create your application with MFC AppWizard (exe) and type SpeakMouth as project name. Click OK button. In Step 1 of MFC AppWizard, choice Dialog based and click Finish button.

Figure 2 : New application.

Figure 3: Application based on Dialog. Click Finish button

2. Setting SAPI on Project

Setting SAPI on this project like the article , "Simple Program for Text to Speech Using SAPI".

3. Building GUI of project

Figure 4: GUI Model

From figure 4, you can build and design like hat. This ID and properties of GUI component:

Model GUI of this project shows on figure 4. After you build GUI, then you must import files bitmap consist of graphics of mouth (figure 5) in Resource View of project. Choice files bitmap in folder res (figure 6). I have put files bitmap of mouth shape in folder res in this project, and you can find these files bitmap in your Speech SDK too. These files bitmap you must import:

• mic eyes closed.bmp
• mic.bmp
• mic_eyes_narrow.bmp
• mic_mouth_2.bmp
• mic_mouth_3.bmp
• mic_mouth_4.bmp
• mic_mouth_5.bmp
• mic_mouth_6.bmp
• mic_mouth_7.bmp
• mic_mouth_8.bmp
• mic_mouth_9.bmp
• mic_mouth_10.bmp
• mic_mouth_11.bmp
• mic_mouth_12.bmp
• mic_mouth_13.bmp

Figure 5: Import file bitmap into project

Figure 6: Choice file Batmap

After you put all files bitmap into Resource View of project, you also must set properties of these files bitmap ie. assign ID of files bitmap. You can do it with right clicking of your mouse into each file bitmap (figure 7) and you'll see window like figure 8. Here's ID of files bitmap:

Figure 7: Setting properties of file bitmap

Figure 8: Properties of file bitmap

4. Coding

There are three classes in this project (figure 8) ie:

• CAboutDlg
• CSpeakMouthApp
• CSpeakMouthDlg

Figure 9: Classes of project

Call ClassWizard  to add variable into class CSpeakMouthDlg, type m_sError as name of variable and its type is CString, protected.

Below steps of coding processes:

1. In the file StdAfx.h, put these code lines for accessing SAPI COM

 #include <atlbase.h>

 extern CComModule _Module;
 #include <atlcom.h>

2. On the class CSpeakMouthDlg, add the code lines at the top of the file SpeakMouthDlg.h

#include "sapi.h"

#include <sphelper.h>


// CONTANTS OF MOUTH

#define CHARACTER_WIDTH     128
#define CHARACTER_HEIGHT    128
#define WEYESNAR            14 // eye positions

#define WEYESCLO            15

    Beside that, add code lines on the top of class CDialog (file SpeakMouthDlg.cpp):

 #define WM_RECOEVENT	WM_USER+101	
 /////////////////////////////////////////////////////////

 // Mouth Mapping Array (from Microsoft's TTSApp Example)


 const int g_iMapVisemeToImage[22] = {
     0,  // SP_VISEME_0 = 0,   // Silence

    11, // SP_VISEME_1,        // AE, AX, AH

    11, // SP_VISEME_2,        // AA

    11, // SP_VISEME_3,        // AO

    10, // SP_VISEME_4,        // EY, EH, UH

    11, // SP_VISEME_5,        // ER

    9,  // SP_VISEME_6,        // y, IY, IH, IX

    2,  // SP_VISEME_7,        // w, UW

    13, // SP_VISEME_8,        // OW

    9,  // SP_VISEME_9,        // AW

    12, // SP_VISEME_10,       // OY

    11, // SP_VISEME_11,       // AY

    9,  // SP_VISEME_12,       // h

    3,  // SP_VISEME_13,       // r

    6,  // SP_VISEME_14,       // l

    7,  // SP_VISEME_15,       // s, z

    8,  // SP_VISEME_16,       // SH, CH, JH, ZH

    5,  // SP_VISEME_17,       // TH, DH

    4,  // SP_VISEME_18,       // f, v

    7,  // SP_VISEME_19,       // d, t, n

    9,  // SP_VISEME_20,       // k, g, NG

    1	// SP_VISEME_21,      // p, b, m

 };

 ////////////////////////////////////////////////////////////

3. On the class CSpeakMouthDlg, add a member method (you just click on right mouse, and choice Add Member Method). Method:  InitMouthImageList()::BOOL, InitializationSAPI()::BOOL and DestroySAPI()::BOOL , all in protected mode. Beside that, Add variables, here's the code lines: 

   CString m_sError;
   BOOL InitMouthImageList();
   BOOL DestroySAPI();
   BOOL InitializationSAPI();
	
   ///////////////////////////////////////////////////////

   // Speech API Variables

	
   CComPtr<ISpVoice> IpVoice;
   CImageList m_cMouthList;
   int	m_iMouthBmp;
   CRect m_cMouthRect;
   ///////////////////////////////////////////////////////

4. Now, you can implement your method that you have created

 void CSpeakMouthDlg::OnDestroy() 
{

    DestroySAPI();
    CDialog::OnDestroy();

}

BOOL CSpeakMouthDlg::InitializationSAPI()
{
    if (FAILED(CoInitialize(NULL))) {
        m_sError=_T("Error intialization COM");
        return FALSE;
    }

    HRESULT hRes;   
    hRes = IpVoice.CoCreateInstance(CLSID_SpVoice);

    if (FAILED(hRes)) {
        m_sError=_T("Error creating voice");
        return FALSE;
    }

    hRes = IpVoice->SetInterest(SPFEI(SPEI_VISEME), 
        SPFEI(SPEI_VISEME));    
    if (FAILED(hRes)) {
        m_sError=_T("Error creating interest...seriously");
        return FALSE;
    }

    hRes = IpVoice->SetNotifyWindowMessage(m_hWnd, 
        WM_RECOEVENT, 0, 0);
    if (FAILED(hRes)) {
        m_sError=_T("Error setting notification window");
        return FALSE;
    }

    return TRUE;
}

BOOL CSpeakMouthDlg::DestroySAPI()
{
    if (IpVoice) {
        IpVoice.Release();
    }
    return TRUE;
}

BOOL CSpeakMouthDlg::InitMouthImageList()
{
    m_cMouth.GetClientRect(&m_cMouthRect);
    m_cMouth.ClientToScreen(&m_cMouthRect);
    ScreenToClient(&m_cMouthRect);

    CBitmap bmp;
    m_cMouthList.Create(CHARACTER_WIDTH, 
        CHARACTER_HEIGHT, ILC_COLOR32 | ILC_MASK, 1, 0);

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICFULL));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH2));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH3));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH4));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH5));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH6));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH7));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH8));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH9));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH10));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH11));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH12));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICMOUTH13));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICEYESNAR));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    bmp.LoadBitmap(MAKEINTRESOURCE(IDB_MICEYESCLO));
    m_cMouthList.Add(&bmp, RGB(255,0,255));
    bmp.Detach();

    m_cMouthList.SetOverlayImage(1, 1);
    m_cMouthList.SetOverlayImage(2, 2);
    m_cMouthList.SetOverlayImage(3, 3);
    m_cMouthList.SetOverlayImage(4, 4);
    m_cMouthList.SetOverlayImage(5, 5);
    m_cMouthList.SetOverlayImage(6, 6);
    m_cMouthList.SetOverlayImage(7, 7);
    m_cMouthList.SetOverlayImage(8, 8);
    m_cMouthList.SetOverlayImage(9, 9);
    m_cMouthList.SetOverlayImage(10, 10);
    m_cMouthList.SetOverlayImage(11, 11);
    m_cMouthList.SetOverlayImage(12, 12);
    m_cMouthList.SetOverlayImage(13, 13);
    m_cMouthList.SetOverlayImage(14, WEYESNAR);
    m_cMouthList.SetOverlayImage(15, WEYESCLO);

    return TRUE;
}

5. In the class CSpeakMouthDlg, the method OnInitDialog() must have the following code for SAPI initialization

// Set the icon for this dialog.  

// The framework does this automatically

//  when the application's main window 

// is not a dialog

SetIcon(m_hIcon, TRUE); // Set big icon

SetIcon((HICON)(LoadImage(AfxGetResourceHandle(), 
        MAKEINTRESOURCE(IDR_MAINFRAME), 
        IMAGE_ICON, 16, 16, 0)), FALSE);

m_sError=_T("");
if (!InitializationSAPI()) {
    AfxMessageBox(m_sError);        
    DestroySAPI();
}

InitMouthImageList();

return TRUE;  

6. In the construction of class CSpeakMouthDlg::CSpeakMouthDlg(CWnd* pParent=NULL)

 m_iMouthBmp = 0;

7. Now, you must create the method to handle the event of converting speech into mouth motion. You can send the message handler ie: WM_RECOEVENT that you have defined as WM_USER + 101. In file SpeakMouthDlg.h, you type:

// Generated message map functions

//{{AFX_MSG(CSpeakMouthDlg)

virtual BOOL OnInitDialog();
afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
afx_msg void OnPaint();
afx_msg HCURSOR OnQueryDragIcon();
afx_msg void OnDestroy();
afx_msg void OnSpeak();
//}}AFX_MSG

// add message handler

afx_msg LRESULT OnMouthEvent(WPARAM, LPARAM); 
DECLARE_MESSAGE_MAP()

and in the file SpeakMouthDlg.cpp, add these code lines

BEGIN_MESSAGE_MAP(CSpeakMouthDlg, CDialog)
//{{AFX_MSG_MAP(CSpeakMouthDlg)

ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
ON_WM_DESTROY()
ON_BN_CLICKED(IDC_SPEAK_BTN, OnSpeak)
//}}AFX_MSG_MAP

// add message handler

ON_MESSAGE(WM_RECOEVENT, OnMouthEvent)  
END_MESSAGE_MAP()    

This is the implementation of the method OnMouthEvent() :

LRESULT CSpeakMouthDlg::OnMouthEvent(WPARAM wParam, 
                                     LPARAM lParam) 
{
    CSpEvent event;  

    while (event.GetFrom(IpVoice) == S_OK) {
        switch (event.eEventId) {
            case SPEI_VISEME:
                m_iMouthBmp = 
                    g_iMapVisemeToImage[event.Viseme()];
                InvalidateRect(m_cMouthRect, false);
                break;
        }
    }

    return 0;
}

8. Now, you add a method to handle the button click (IDC_SPEAK_BTN) event. Type OnSpeak as the name of the method, and add these code lines as it's implementation:

 void CSpeakMouthDlg::OnSpeak() 
 {
    UpdateData();
	
    USES_CONVERSION;
    IpVoice->Speak(m_sText.AllocSysString(), SPF_ASYNC, 
        NULL);		
 }

9. So, you can debug and run your program

5. Testing

To test your application program, you can run it and type word a into the Edit Box. After that, click the Speak button.
