Abstract
<p>The purpose of this study is an acoustic survey of intonation in a set of declarative and interrogative sentences as uttered by 15 children with severe autism (SA) in comparison with 15 Typically Developing (TD) children. The results indicate that monotony is not a common feature in the speech pattern of all autistic children. More specifically, the results demonstrate that the monotony attributed to the autistic children’s production of speech cannot be attributable to all kinds of sentences they produce as they can produce statements and questions fairly similar to typically developing children.</p>

Autism is a complex, multi-faceted disorder that affects the neurodevelopment of human beings during their early stages of life and for many lingers throughout adulthood
The results demonstrate that the monotony attributed to the autistic children’s production of speech cannot be attributable to all kinds of sentences they produce as they can produce statements and questions fairly similar to typically developing children
As the focus of previous studies in our line of study had been the production of prosody and intonation in children with High Functioning Autism (HFA) and Asperger Syndrome (AS), we chose to concentrate on children with severe autism instead
Summary
Multi-faceted disorder that affects the neurodevelopment of human beings during their early stages of life and for many lingers throughout adulthood. One of the abnormal features of autism is the deficit in nonverbal communicative behaviors, manifested by absent, reduced, or atypical use of eye contact (relative to cultural norms), gestures, facial expressions, body or speech intonation The research of scientists such as Kenner (1943), Bogdashina (2005) and Gallo (2010) shows that there is an abnormality in the prosody of autistic children. They have a monotone intonation and they cannot change intonation when they want to ask a question or produce a statement. In this research we had two aims for investigating intonation in autistic children: to find out whether autistic children produce intonation in statements and questions with a monotone intonation; and to find out whether the monotone intonation is a common feature among all autistic children
