I'm posting it here, because I'm almost sure it's forced by localizers. Apparently Xenoblade X won't let you switch the voice language for about first 30 minutes. You're forced to listed the dub, create the character with dub voices and then listen to few cutscenes dubbed.
It doesn't work like in other games that had this kind of crappy solution.
First of all, the option menu is accessible when you're launching the game for the first time. You can switch any option EXCEPT the voice language.
Skipping the cutscenes, and setting original voice and starting anew game won't do the trick because the game is switching back to dub. So you're basically locked with dub no matter what you do and you'll never be able to heat original voice acting in the beginning of the game. It's ridiculous. There's zero technical reasons to do this. I'm really sure it was forced by localizers.
