Question about Background Singing in Voyage

[Grantith]

I've been listening to the instrumental version of Voyage listening especially to the background singing. It sounds like a small choir or a small group of people singing together. I've been trying to figure out what they are saying, lol. I swear that it sounds like English, but I can't make out what they're saying. Has anyone else noticed this or have any ideas about what they might be singing? Thanks for any help! lol, this is sort of a silly topic, but oh well.
