Definition
Prosody is the music of speech, its rhythm, melody, pitch, stress, and intonation. It is how we say something, not just what we say. Autistic people may have prosody that sounds different, flatter, more singsong, or with unusual emphasis, and may also find it harder to read the emotional meaning others pack into tone of voice.
Why It Matters
Prosody carries a lot of social meaning, so differences here can lead others to misread an autistic person's feelings or intentions. Understanding this helps parents advocate against assumptions that a flat or unusual tone means a child does not care or is being rude.
Common Misconception
A common myth is that unusual intonation shows a lack of emotion or interest. In truth, an autistic person can feel deeply while their voice carries that feeling differently, and tone should never be taken as proof of what someone does or does not feel.
