Hey, this looks really nice and worked like a breeze for French!

Question: out of the processing steps you mention - transcription, quality filtering, segment selection, and (I guess) wrong-word selection) are there any truly manual steps? Those would be the ones that prevent you from building this for just about any language that has good transcription available, right?

There are no manual steps. But it is hard to gatekeep quality. The transcription models work well for the large languages but not so much for the smaller ones.
