Also, check for sentence structure. After replacing each word, the sentence should still make sense. If a replacement doesn't fit, maybe find a better synonym. For example, "cater" can be "suit|accommodate|serve", which all fit the context. "Observers" is a synonym for viewers, which is okay
"or another language of their choice" "or another dialect of their preference|or a different language of their choosing|or another language of their choice".
