A pangloss was a five-to-six-hundredth-century invention. It automatically translated the speech of one person into the language of another through mental telepathy. The effect could be described as hearing the person's voice between one's ears rather than with them. Also, the motion of the speaker's lips did not necessarily match the sounds the listener heard, rather like that of a badly dubbed foreign film. Lasoporp Rof used a pangloss to communicate with T.G. Kahn.
