Is it possible for us to get V/O of a different language without a 3rd party software?

I know this is selfish and quite greedy of me, but I feel as if this should've been done a while ago. League of Legends has evolved into such a worldwide game that I feel they need to add languages to the game. Especially in the United States where it's very diverse. And if they add language why not add the different voice overs as well. Blizzard has been doing it for years and I believe it is time for league to have something like this. I think it would add to the overall enjoyment of the game!
