Accommodative phonostylistic variation in conversational interaction

Within the framework of communicative accommodation theory, this study investigates the phonostylistic behaviour of French native speakers engaged in casual conversation. It examines some of the features speakers use to structure their discourse, particularly prosodic responses to the interlocutor and interaction management devices. Part One gives an outline of previous research in the fields of conversation analysis, prosodic analysis and accommodation theory. These insights are developed in Part Two into a framework that allows investigation of the following hypotheses: Accommodation and prosodic variation at topic change: this study examines the role of accommodation and prosodic variation as they occur at topic change in four case studies. The management role of the pause at theme change will operate above the consensual/non-consensual categories, and hence variation in terms of melodic difference will be greater at such pauses. By examining the thematic structure as it is reflected in prosodic behaviour around the pause by both speakers, the study demonstrates that at topic change there is a marked difference in the size of melodic gap in Hz around the pause. Accommodation and prosodic variation by length of pause: It is contended that in consensual dialogue, the longer the duration of the empty pause which divides two consecutive turns, (1) the less the difference in intensity (dB) between the two speakers, and (2) the greater the difference in f0 between them, despite differences in their own vocal range. In non-consensual dialogue, it is contended that in instances where dispute or thematic refusal occurs (as witnessed through lexical indices), inversion of the two hypotheses above is possible. It was found that speakers can converge by matching each other’s pitch or by following a speech pattern whereby they both rise at small but regular intervals forming a smooth pattern in general pitch direction.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
