Abstract:
This paper reports on a conversation-analysis case study of interaction between a child with cerebral palsy and an adult using a computer-based voice output communication aid (VOCA) device with a touch-sensitive screen-input system. Data was collected from video recordings of everyday activities at school. The public nature of the VOCA-mediated turn construction process (hand movements towards the screen, on-screen folder navigation, synthetic speech) displays the projection of the turn under way and its possible continuations. The adult interlocutor orients to such projections when contributing to the topic of the ongoing turn and when initiating repair on its topical development. Contributing may activate the AAC user's further involvement in the ongoing turn, while repair may restrict the AAC user's influence on the topical progression. The findings are relevant for clinical assessment and intervention.
