Qt Code: 
  1. QTextToSpeech *tessi = new QTextToSpeech(this);
  2.      QVector<QLocale> localein =  tessi->availableLocales();
  3.      QTextStream out(stdout);
  4.        out << "QTextToSpeech availableLocales \n";
  5.  
  6.        foreach (const QLocale &locale, localein ) {
  7.                int nr = (int)locale.language();
  8.                QString country = QLocale::countryToString(locale.country());
  9.                QString name(QString("%1 (%2)")
  10.                             .arg(QLocale::languageToString(locale.language()))
  11.                             .arg(locale.bcp47Name()));
  12.                QVariant localeVariant(locale);
  13.                out << "Lang Found:" << nr << "-" << name;
  14.                out << "\n";
  15.  
  16.          }
  17.        out << "end... \n";
