So what I'm writing is about a group of humanoid aliens who discover Voyager 2, a probe with a record containing information about Earth. This is supposed the be their first exposure to it, so they didn't know English before. They have their own language and everything, but the dialogue is in English for obvious reasons. I'm very early on into my first draft, and they have figured out how to actually play the record, but my problem is, how are they supposed to understand the English messages? They eventually will get to Earth, and they will communicate through a translation device, but that device scans your brain to see what sounds are associated with what concepts and basically downloads the language. The problem is, the record is a recording, so they can't do that. There are also pictures encoded in binary pixel values within the sound file, which they can view and see what Earth is like, but that's really not enough, because the speech on the Voyager 2 record (A real thing, look it up) is actually quite moving and would make for a powerful scene if the aliens understood it. Ideas?
