One thing that autistic kids can have trouble with is something you probably do every day without thinking - varying your voice as you speak to help get your message across. You change the pitch, volume, speed and rhythm of your speech - making your voice go up when asking a question, using inflections for sarcasm or stressing words to add emphasis - to ensure that your intended meaning is clear to the person that you're talking to.
These areas of speech are called prosody, and autistic kids can struggle with it - talking too loudly, using a monotone voice or asking questions in a flat tone - and as a result are often mistaken for being disinterested, unfeeling or lacking a sense of humour.
So why is it hard for them, and how can you help to prevent these misunderstandings?
