Since a couple of days there is something strange with Google Maps. I used to have a rather pleasant female voice when navigating. Since a few days I have two voices: the old one and a new one, a rather shrill female voice. Usually I hear the new voice when navigating, but sometimes the old voice comes back for 1 or 2 sentences. I have already checked the TTS settings: my language is properly selected and the installed voice is the new shrill voice. Who knows what is going on and what can I do about it? I'd rather have the old voice back.
