A second element in the universal translator field is often the consideration of translating human languages such as English to an alien language and vice versa if we were to encounter them in the future. The process for this would be even more complicated then translating between different languages that exist on Earth and would certainly require some cooperation and perhaps some burrowed technologies from other alien species to achieve this. This area is entirely speculative at the moment and this topic tends to be discussed among science fiction fans and futurists for the most part but is interesting none the less.
