I would like to listen the original english voices with subtitles and menu in my language, spanish.

Could we get a language selector?, right now we can play the game in english or spanish, we can't mix. Deus Ex developers patched this possibility in Human Revolution and is awesome.
And btw, every time we change the language in Steam properties the damn thing downloads 1 GB.

Yes, when you change languages, you have to re-download a large part of the content. You can not mix languages. If you want to hear it one language, you have to read it in that language. This is all normal for this game.

I am not even sure if it can be modded in. But that is where I am moving this as that is where you may find if it can be done.

It probably COULD be modded, but it would take an extremely long time to replace all of the English subtitles with Spanish ones.

Um... Shouldn't it work like this?

Backup Spanish Skyrim.esm
Switch to English on Steam
Restore Spanish Skyrim.esm

Nice avatar...

You have a point actually.

The spoken dialogue are stored in a separate sound library (.bsa?) on Oblivion. Backing up the English library and replacing the sound library on a Spanish install would give you Spanish subtitles with English voiceovers

I would love it if Bethesda eventually were to release a pack that you could download and alter your game to another language, especially spoken dialog. I enjoy learning other languages and for FIFA on the 360 I had German, French, Italian and Spanish all downloaded, and mostly played in German since I was learning it (and still am) at the time.
