Prosodic Effects of Discourse Salience and Association with Focus

Three factors that have been argued to influence the prosody of an utterance are (i) which constituents encode discourse-salient information; (ii) which constituents are contrastive and evoke alternatives; and (iii) which constituents interact with the meaning of focus operators such as only (i.e., they ‘associate’ with focus). One challenge for a better understanding of the prosodic effects of these factors has been the difficulty of finding a way to evaluate hypotheses quantitatively, since individual variation in productions is often large enough to wash out experimental effects. In this paper, we apply a methodology introduced in [1] which regresses out subject and item variation, uncovering otherwise hidden prosodic patterns, and show how the three factors interact in sentences containing single or multiple foci.
