This paper presents a case study which describes, compares and contrasts the prosodic features of the intonation of two children diagnosed with High- Functioning Autism (HFA) with two children without developmental disorders (WDD), matched for age, school grade and academic achievements. They were all male monolingual speakers of Modern Hebrew. Three prominent components of prosody (intonation units, simple pitch accents and edge tones) were examined in two elicitations tasks (spontaneous speech and reading-aloud). The data were transcribed and described using the Autosegmental-Metrical (AM) theory and the results were analyzed and explained according to the theory of Phonology as Human Behavior (PHB).
