The structure of participants' turn-transition practices in aided conversations that use speech-output technologies

Using the concepts and principles of conversation analysis (CA), this paper examines the everyday, unscripted, spontaneous conversations between 4 males who communicated with the aid of speech-output technologies and their mothers. The analyses focused on describing the conversationalists' various actions in aided turn-transition processes, resulting in a 3-part turn-transition structure used to accomplish aided turn initiation. Despite the challenges to conversational progress, the participants did not consider the conversational speed a challenge. The participants and their mothers were oriented to the progression of the aided conversation by creating interaction practices to achieve successful turn-transitions. By understanding the structural characteristics of fluent aided conversations, it may be possible to develop effective interaction strategies for communication partners and for augmentative and alternative communication technologies that are intentionally designed to facilitate interactive communication.
