Pitch range declination and reset in turn-taking organisation

Céline De Looze, Irena Yanushevskaya, John Kane, Ailbhe Ní Chasaide

In this paper, we investigate how pitch range declination and reset contribute to turn-taking organisation. We (i) investigate the effect of the unit position in a turn on its pitch range as well as (ii) compare the difference in pitch range between consecutive units that are separated by a gap vs. a pause. We also (iii) test the effect of the number of speech units in a turn as well as the turn duration on the peak height at the beginning of the turn. Our results suggest a pitch range declination trend between the Initial and Median speech units of a turn but a violation of this declination for the Final units of the turn. Consequently, the difference in two consecutive units’ pitch range is found larger at pauses than at gaps. Our results also show that the higher the number of speech units in a turn or the longer the turn, the higher the peak height. Our findings particularly reveal that the distance between the pitch range level and its upper limit may be a salient cue in projecting the end of a turn. We discuss our findings along the debate on Projection and Reaction theories and that of Hard vs. Soft pre-planning of speech production, and address how these findings may be useful for human-machine interactions.
