The goal of this work is to study the acoustic differences of areas surrounding the two kinds of shared enjoyment instances, called “social zones”, using data collected from children with autism, and their parents, interacting with an Embodied Conversational Agent (ECA). A classification task was performed to predict whether a “social zone” surrounds a voiced or an unvoiced laughter instance.
