This article proposes an analysis of the gestural production of people suffering from fluent or non-fluent aphasia in comparison with the gestures performed by speakers not suffering from any language disorder. The interest of such a study is twofold: firstly, it allows a better understanding of what happens to gestures during the numerous speech dysfluencies caused by the speech impairment. Among other things, it sheds light on the links between speech and gestures in multimodal face-to-face interaction. Despite the profusion of (...) work on aphasia, very little is still known about the characteristics of the gestures performed spontaneously by aphasic people. The study presented here is based on video examples from the AphasiaBank corpus to illustrate the specific features of the speech and gestures of atypical speakers and gives a more detailed description of the gestural production of people with aphasia. This knowledge can inform post-stroke rehabilitation procedures that rely on some form of multimodal speech therapy in order to adapt to the various communication needs of the patients. (shrink)
