Dialogue and Localization System

So in our game is planned for English and Japanese language. It’s just a simple vocal in which it produce “Yeahhh” in English and “Yataaa” in Japanese. So there’s a lot of variation of it inside the game.

My question is that how to set up in which when players choose Japanese or English language. It pinpoints to that banks for the usage throughout the whole game. Anyone got any tutorial or a simple system they manage to do before.

Thanks in advance.
