Prosodic gives a lot of information relevant to understanding of spoken messages. In addition, prosodic in signaling understanding in language interaction. The aim of this study was to point out, the possible recurring patterns in the pitch contours of children in autism. This project was the development of an analysis or synthesis tool in PRAAT that extracts prosodic features from a speech signal and furthermore, creates a syntactic signal consisting of these features only. We give a description of the prosodic analysis, and implementation details and discuss its feature extension capabilities as well. The results of the present study showed that prosodic in its conversational context is useful in order to reveal possible functions of features that would have been overlooked with a more deficit prosodic in autism.
