Prosodic contextualization of minimal responses to yes/no-questions in aphasic talk-in-interaction: a descriptive single-case study of a Norwegian aphasic speaker.

The article explores aspects of the role of prosody as a contextualization cue in aphasic conversation through auditory and acoustic analysis of an aphasic speaker's use of pitch variation in responses to closed yes/no-requests. The results reveal two prosodic realizations of 'yes' and 'no' contextualizing different kinds of responses: a flat realization with no prolongation and minimal pauses, signalling decisiveness, and a realization with movement in pitch, prolongation and preceding pauses, signalling indecisiveness. The analysis also shows how the aphasic uses a particular realization manipulatively for interactional purposes. The study illustrates the vital role that seemingly unimportant details play in the co-constructive process of creating meaning in interaction. The results indicate an area of competence that seems undisturbed in this speaker.
