I have brainstormed with the global chat for a few minutes before coming up with this.
So let's say, we have youtubers all across the globe promoting icarus, like Khovansky and Madyson, sure muse made special costumes for them, but that didnt really help solve the fact that when their foreign playerbase floods in it's likely for them to be unable to communicate in the language their captain might be speaking in, thus creating language barriers and possibly being detrimental to their vessel for that very reason. Voice commands can do the trick, but they're not the most reliable considering some of them are inevitably less eye friendly than others (See: Man-guns commands) I understand muse is not the most ethically diverse indie company and does not have the manpower to add more languages in the voice commands.
However, the community may. What I propose is an official competition that allows players to submit their own voices in their native languages. If there are multiple of the same languages, best one(s) get added into the game. If there's only one submission for a certain language then they're added right away with no catch. I think this would be a grandoise addition in the game that can easily be implemented.
