Is it possible to set preferable language(s) for youtube?

[LightTemplar]

I find out, there are videos with translated description and title for many languages. If I open it in my account, I see it in my preferable language. If the script gets it, it gets in original language. You can check it for example with this video: https://www.youtube.com/watch?v=9IQZIdpJ05Q - it's Italian, but I would like to have it in English or German.

So, would it be possible to set preferable language or languages for the script?
