"A poly-vox is a specialized computer that can be worn around the throat. It translates a message that it hears in one language into another language, and then repeats it. It can learn an unknown language if it can be programmed with key phrases, and then exposed to the language for 1-100 hours (see Language). A character does not need computer skill to use a poly-vox." The Poly-Vox weighs 1 kg and costs 1,500 Cr. All Polyvoxes can be interfaced with computers equipped with a language program for uploading a new language or downloading a language from files.
