It actually would be somewhat feasible I think to set up a utility to do that as you watch something. Might require a plugin or 3rd party tool to streamline the process though.

The idea being that it could do that for whatever you're watching ahead of time, so long as it had access to the original Japanese captions.

Audio/voice localization might take a little more doing though, but we're not too far off from making that doable. Could maybe even generate vocalizations based on the original Japanese voice actors (I know that's already a thing, regardless of language barriers, but I don't know if it's quite fast enough for the scenario we're talking about here).
