Is there a way of searching YouTube for videos with captions in specific languages?

Question

I know about using the "cc" operator, as in:

Monkeys, cc

but what if I only want videos about Monkeys with Vietnamese (soft-coded) subtitles?

I've tried cc=vi, cc:vi... none seem to work.

Answer 1

One way to achieve this is to: (a) use the CC search filter, and then (b) use the new auto-translate feature in which you can translate into any language.
