Wow! That’s so cool!
Edit: I just tried it for a couple shows that didn’t have Korean subs (my target language), and it works well!
As David_Wilkison said with Hungarian, this seems true with regards to Korean (the one I tried and so far as I can tell as more of a beginner learner):
I noticed that using it to get subs of shows in my target language (that don’t have original audio subs)—even though a VPN set to another country might also get me target language subs—means I don’t get every piece of spoken dialogue with the Whisper model. Still, I get enough that it works for me.
