German voice of Hanzo is NOT Otto Waalkes. It is Bernd Vollbrecht: https://www.tiktok.com/@notizblatt/video/7181058017268436229 - You could scrape his movies for more dataset material, e.g. 2021: Catweazle. In any case, if your goal was a realistic interpretation of Otto Waalke's voice, then you must at least remove the Hanzo voicelines from the dataset.

This models output also sounds detuned, I couldn't bring it in tune with Instrumentals by pitch shifting.
