I’m probably the odd man out in that I like to listen to dubs in languages I don’t understand. So from a translation/accuracy point-of-view, I’ve got nothing to add. However, I have some opinions:

I like Soviet-style voiceovers, at least in principle. You get to hear the original performance exactly as it was, and also a translation in a more-or-less neutral voice. It is oddly similar to listening to a speech at the UN, though. It also helps that the Russian non-voiceover dub of Star Wars has such awful audio quality that it’s easy to prefer the voiceover dub in that case.

Leia and Threepio are apparently hard to capture, tone-wise, in a dub. Leia is a strong take-charge female lead, not a delicate love interest. I feel like the Thai dub completely misses Leia, while the Navajo dub gets it right. On the other hand, Threepio is basically a butler – someone who is polite to the point of obsequious, while at the same time just barely papering over the fact that he often feels he’s smarter than the people he serves. Lots of dubs fail here, just making Threepio Some Dude with vocal distortion, but IIRC Hindi does a very good job here.

Then there’s Tamil. I love that crazypants Tamil dub. Characters who are onscreen but not saying anything get a Tamil breathing track, sometimes every bit as noticeable as Vader or Admiral Ackbar’s breathing. Don’t speak English or have English subtitles for what you’re saying? Not a problem, you’re getting dubbed anyway. Even Ewoks get fresh new voices, but I honestly can’t tell you if it’s Tamil or not. And I’m pretty certain there’s English peppered into the Tamil*, so you can hear Luke tell R2 to shut up, or Han tell Luke “I hate you”. It actually works in context. I heart this dub.

* I’m not talking about bits where there’s a gap in the dub and we fall back to the English track, although there are those as well, but places where the Tamil voice actors use English phrases.
