Is this same-language, or does it work for translated subtitles?

I have some Korean TV DVDs with Japanese subtitles I was trying to use as a guide for adding in US subtitles that came from a different source. I assumed that aside from commercial break timings (one break in the middle) and start/end gaps they should be the same, but my results automating based on timing clusters didn't work too well. Some subtitles were split into multiple segments, sometimes grunts or ambient noise had subtitles, etc.

I might try this out.

The model was trained with features of human voice bound to a frequency range so it may work for "cross-language" sync. Why not give it a go and check the quality? It won't change the content of original segments but only shift them along the timeline if there are gaps.

Just realised another user reported that it did not work well for Russian movie and Polish subtitles. Nonetheless, it doesn't stop you from training your own subaligner with those media assets you possess.

Looks like it's language-agnostic (or at least ALASS is).
