I am the robot.[If Soundwave doesn't have prior experience with humans before he'll find it extremely offensive to be called that. Still, he should correct him just in case he meets another Cybertronian. Some won't take it as well as Soundwave will.]

I would refrain yourself from calling us robots the next time you may encounter my kind. Some do not take well to be refer to as a mindless machination. [He speaks those words as much venom as he could muster.] We are just as much of a person as you are.
