The Webshifter Series might be a good start (Book 1 is Beholder’s eye). The main character is a shape shifter, so we get to see the world from the point of view of someone who can change her form between different alien races. The book has a lot of interesting descriptions about her changing senses, e.g. suddenly being able to perceive different colors or having an organ to feel the magnetic field etc.
That’s a cool concept, hadn’t heard of it. Nanotech might also be an option for this. You have a bunch of nanobots in your brain and when you encounter a new language, some AI will decipher it and rewire your brain to understand it.
