Question about a procedure

Hi,

I have a form with a listbox on it (lbVoices), where the speech-engines will be loaded.
and a small richedit (reText) where the user can enter text that he/she would like to test.
and a test-button (TestBtn). And 3 trackbars for the volume, pitch and rate
(tbVolume, tbRate and tbPitch).

I have this procedure for the TestBtn:

procedure TSettingsDlg.TestBtnClick(Sender: TObject);
begin
If TestBtn.Caption = 'Test' then
begin
TestBtn.Caption := 'Stop';
SpVoice1.Speak(reText.Text, SVSFlagsAsync);
end else begin
TestBtn.Caption := 'Test';
SpVoice1.Skip('Sentence', MaxInt);
end;
end;

This procedure works great. Only I forgot to tell
this procedure that he has to speak the selected item in the listbox (lbVoices)!!!
who knows the answer and is willing to help me.

P.

you question doesn't make sense

does it have to use the selected voice to speak the text from the rich edit ?

Peter Kiers

ASKER

Your right. How dumb of me.

If my speechengines where loaded in a treeview instead of listbox my
problem would be solved. Do you know the answer?

Emmanuel PASQUIER

Do you care if I rephrase what we think you asked ?

" This procedure should use the voice selected in the listbox (lbVoices) "

Well, I suppose that if you click in the listbox, the voice is selected by your LbVoicesClick method ( that can be simplified by the way, see below)

So it' might be possible that what you say is that AS LONG AS YOU DON'T CLICK ON A VOICE, the procedure above does not use the right voice. and that is because in your procedure TSettingsDlg.LoadSettings; when you set the listbox item index, it does not trigger the Click event as an onChange event would on a combo box. You have to call it manually after

procedure TSettingsDlg.LbVoicesClick(Sender: TObject);
begin
 SpVoice1.Voice :=  
   ISpeechObjectToken(lbVoices.Items.Objects[lbVoices.ItemIndex]);
end;

procedure TSettingsDlg.LoadSettings;
var 
 ini: TIniFile;
 defVoice: string;
begin
 ini := TIniFile.Create(SettingsFile);
 try
  if lbVoices.Items.Count > 0 
   then defVoice := lbVoices.Items[0]
   Else defVoice := '';
  lbVoices.ItemIndex := lbVoices.Items.IndexOf(ini.ReadString('Voice','Voice', defVoice));
  tbVolume.Position := ini.ReadInteger('Voice', 'Volume', SpVoice1.Volume);
  tbRate.Position := ini.ReadInteger('Voice', 'Rate', SpVoice1.Rate);
 finally
  FreeAndNil(ini);
 end;
 LbVoicesClick(lbVoices); // <== here set the selected voice
end;

If my speechengine would be loaded in a treeview, my problem is solved:
Here in this procedure the speechengines get loaded in a listview:

procedure TSettingsDlg.FormCreate(Sender: TObject);
var
I: Integer;
SOToken: ISpeechObjectToken;
SOTokens: ISpeechObjectTokens;
begin
SettingsFile := ChangeFileExt(Application.ExeName, '.ini');
SpVoice1.EventInterests := SVEAllEvents;
SOTokens := SpVoice1.GetVoices('', '');
for I := 0 to SOTokens.Count - 1 do
begin
SOToken := SOTokens.Item(I);
lbVoices.Items.AddObject(SOToken.GetDescription(0), TObject(SOToken));
SOToken._AddRef;
end;
tbRate.Position := SpVoice1.Rate;
lblRate.Caption := IntToStr(tbRate.Position);
tbVolume.Position := SpVoice1.Volume;
lblVolume.Caption := IntToStr(tbVolume.Position);
LoadSettings;
end;

sorry i ment listbox

Peter Kiers

ASKER

OR what I ment by the question:

At the startup of my programm the speechengines are loaded into the listbox.
and one is selected from the inifile.
f.e: Anna
Clair <= Clair is selected
Peter

When I press the TestBtn the programm uses the speechengine Anna
and not Clair!

When I choose one and the press the TestBtn, then i get right.
P.

Emmanuel PASQUIER

read my former post again. Your problem is that you don't call
LbVoicesClick(lbVoices); // <== here set the selected voice

when you load the ini file

Peter Kiers

ASKER

Incompatible types: ISpeechObjectToken and TObject

Peter Kiers

ASKER

Thanks Espasquier this is the answer:

procedure TSettingsDlg.LbVoicesClick(Sender: TObject);
var
SOToken: ISpeechObjectToken;
begin
begin
SOToken := ISpeechObjectToken(Pointer(
lbVoices.Items.Objects[lbVoices.ItemIndex]));
SpVoice2.Voice := SOToken;
end
end;

procedure TSettingsDlg.LoadSettings;
...
tbRate.Position := ini.ReadInteger('Voice', 'Rate', SpVoice2.Rate);
finally
FreeAndNil(ini);
end;
LbVoicesClick(lbVoices); <==== I just had to add this
end;
