Sorry if this belongs elsewhere. I have several alien characters who need to talk with english speaking human characters. I didn't want to use a cop out like the babelfish, so I have them learning new methods of communication super quickly, as a part of their alien nature. Kind of like Dr. Ransom in Out of the Silent Planet 2 questions: how much made-up alien language could readers tolerate in dialogue? And, could I likely get a suspension of disbelief freebie if I just landed them on Earth speaking perfect English?
