I tried Urdu. The music quality seems good but the pronunciation is wrong (e.g. slight aa sound instead of ee sound) for many simple common words and helper words. But I don't understand why its wrong. If its trained on lots of Urdu/Hindi music, no one pronounces those words like that. How does it get the a/e wrong while still singing almost correctly? It's weird.
