Tangentially-related: When YouTube auto-dubs now, I noticed that Spanish language get dubbed in a Spanish-inflected accent, and French language similarly (I think).

Is it likely that they are using a model like this? Or are they actually trying to voice clone the original and then translate to English? I'm not even sure if the few Spanish-accented English auto-dubs I've heard are the same voice or not.

(Actually, that reminds me of growing up in Italy, where for a long time all English movies were shown dubbed, not subtitled, and they had the same lead male voice for all male leads, and the same lead female voice for all female leads, across every movie. I can still hear those voices in my head now thirty years later...)
