And here is a sample from the demo that is included with the wrapper:
procedure TForm1.TttsOnInitListener.onInit(status: Integer);
var
Result : Integer;
begin
if (status = TJTextToSpeech.JavaClass.SUCCESS) then
begin
result := FParent.tts.setLanguage(TJLocale.JavaClass.US);
if (result = TJTextToSpeech.JavaClass.LANG_MISSING_DATA) or
(result = TJTextToSpeech.JavaClass.LANG_NOT_SUPPORTED) then
ShowMessage('This Language is not supported')
else
begin
FParent.Button1.Enabled := true;
FParent.button2.Enabled := false;
end;
end
else
ShowMessage('Initilization Failed!');
end;
procedure TForm1.SpeakOut;
var
text : JString;
begin
text := StringToJString(Memo1.Lines.Text);
tts.speak(text, TJTextToSpeech.JavaClass.QUEUE_FLUSH, nil);
end;
