Auditory-visual Perception of VCVs Produced by People with Down Syndrome: a Preliminary Study

Abstract : Down syndrome (DS) is the most frequent genetic disorder in humans and is present throughout society. When questioned about their child’s speech, all parents of a child with DS report speech intelligibility issues [Kumin, 2006]. People with DS actually have better receptive than expressive speech abilities [Kumin, 2006]. Improving speech production of people with DS is an important aspect of their quality of life. Understanding how perception of speech produced by people with DS could be improved could also have positive effects on their social integration.Speech difficulties in people with DS originate from anatomical and physiological specificities as well as motor impairments and appear in early childhood. For example, people with DS have a smaller vocal tract and their tongue is bigger relatively to the size of their oral cavity. Other anatomical and perceptual specificities affect their ability to produce speech (see [Kent and Vorperian, 2013] for a review). All these specificities must not only have acoustical consequences but also visual ones.To our knowledge no study has explored auditory-visual perception of speech produced by people with DS whereas it is well known that speech perception benefits from the addition of vision especially in disturbed conditions (for example in noise: [Sumby and Pollack, 1954]). This study aims at exploring if and how vision can improve the perception, by “ordinary” people, of speech produced by people with DS.
