How can I easily find all languages a show has been dubbed into?

Question

I usually only watch anime with the original Japanese voice actors, since I've had bad experiences with dubs in the past. However, I'm sometimes interested in watching a show dubbed in something that isn't Japanese, and moreover, I want to know if there are any alternatives to English dubs.

Is there any site that will let me see all languages a show has been dubbed into efficiently?

• MyAnimeList gives the voice actors in various languages for characters. However, this information is often incomplete. For instance, I just looked at the page for Nagisa Misumi of Pretty Cure and noticed that no Cantonese voice actress is listed, even though a Cantonese dub exists.

• A Wikipedia article in some language foo for a show will sometimes list any voice actors for the dub in foo in addition to the Japanese voice actors. Information about dubs in other languages is generally lacking. This would mean that I would have to check (and be able to read) each Wikipedia page in each potentially interesting language. Moreover, I would have to carefully check shows one at a time, which is not convenient.

• Similarly, wikis for a series sometimes contain information about dubs (e.g. a Sailor Moon wiki I found). As a general rule however, this is not the case. For instance, a Cantonese dub for Revolutionary Girl Utena exists, but there is no mention of it in a fan-made wiki.

In the case of Cantonese (or even Mandarin), I can usually "guess" that older, more prominent shows will have a dub. However, I find it difficult to do the same for other languages that I might be interested in (e.g. German), and at any rate, it'd be nice to not have to rely on my guesswork.

Answer 1

Translating web pages automatically with Google Translate°

This would mean that I would have to check (and be able to read) each […] page in each potentially interesting language.

Google Translate goes a long way in helping that. Although unfortunately its translations of Asian languages can still be tricky to understand.

If you use the Google Chrome browser, it should automatically offer to translate foreign pages (but does not consistently do so for me).
If you want to test that, here's the Cantonese Wikipedia page for Pretty Cure:
https://zh-yue.wikipedia.org/wiki/Fresh_Precure!

If you use another browser, e.g. Mozilla Firefox, or Chrome doesn't offer the translation by itself:

Put this before the URL to translate:                               https://translate.google.com/translate?&u=

Example: https://translate.google.com/translate?&u=https://zh-yue.wikipedia.org/wiki/Fresh_Precure!

° Sorry this is not an answer to the question, but I find it so important, that I wanted it to be more visible. (And then I ended up writing more than would fit into a comment.) If the community objects, I will move this to a comment.

In relation to the question, the translation enables you to apply the useful approach, suggested by the asker, of consulting the anime's page on the Wikipedia(s) of your desired dub language(s). (Or opening foreign Google results.)

Answer 2

Googling specific dub languages

Example: https://www.google.com/search?q="cantonese"+dubbed+pretty+cure

(Putting single search terms within " double quotes  makes sure they are actually present in the results. (You could also apply that to the word dubbed.))

This tends to return YouTube videos of the Opening songs if the dub exists. (Don't get confused by fandubs though.)
