Training autistic brains to recognize visual and vocal cues

To understand the meaning of a conversation, kids automatically do what adults do - besides processing the meaning of words, they unconsciously "read" the expression on a person's face and listen to their tone of voice, then integrate that information with the context at hand to discern meaning, be it humor, anger, irony or straightforwardness.
