We've seen real-time translators before, but this is the first time we've seen one designed to preserve a language rather than just make it possible for overseas Americans to understand people. The Voxtec International Phraselator P2 is currently being used by the Prairie Island tribe in Minnesota to pass on the Dakota language to future generations.
The translator easily and accurately translates English into their native language on the fly. The device is already in use heavily in Iraq and Afghanistan by troops communicating with locals, so it's only a matter of time before we get this type of technology built into our cell phones so Americans can be even more conspicuous while traveling overseas. "I… SAID… I… WANT… A… CHEESEBURGER." Wonderful.
