Q: Qt - [c++] Qt6 TextToSpeech does not use Localization

kevin_d

Hello everyone!

Ich ported my project to Qt6. In the Windows build, everything works fine, except that the TextToSpeech engine does not speak English anymore (which worked in Qt 5.15.2).
I used the following function. Explanation: I try to switch randomly between different voices. (In Windows i usually have only one voice).

What's wrong?

void SpeechClass::say(QString text, bool )
{
    if (text2Speech == nullptr)
    {
        QLocale::setDefault(QLocale(QLocale::English, QLocale::LatinScript, QLocale::UnitedStates));
        text2Speech = new QTextToSpeech(this);
        text2Speech->setVolume(0.88);
        text2Speech->setLocale(QLocale(QLocale::English, QLocale::LatinScript, QLocale::UnitedStates));

        QVector<QLocale> _l = text2Speech->availableLocales();
        int num_locales = _l.size();

        for (int loc = 0; loc < num_locales; loc++)
        {
            if (_l.at(loc).language() == QLocale::English)
            {
                text2Speech->setLocale(_l.at(loc));
                QVector<QVoice> _v = text2Speech->availableVoices();
                int num_voices = _v.size();
                int __v = rand() % num_voices;
                text2Speech->setVoice(_v.at(__v));
                break;
            }
        }
    }
    text2Speech->setLocale(QLocale(QLocale::English, QLocale::LatinScript, QLocale::UnitedStates));
    text2Speech->say(text);
}

best regards, kevin_d

The speech output seems to have german phonetics (My Windows is a german installation).
