Discourse-Related Effects on Speech Durations: A Challenge for Models of Speech Production

Caroline L. Smith


With topic labeling providing an analysis of the text's organization, the experiment reported here investigated the relation between the structure of the text and the durational patterns produced when it was read aloud. Durations were chosen for study in part because much previous work has concentrated on F0. In addition, acoustic durations in English are known to be affected by segment identity and local context in a way that F0 is not, so it is interesting to see whether, like F0, durations are also affected by the overall organization of the discourse. The present paper focuses on the interactions between discourse organization and durations, and how these may reveal drawbacks in current models of speech production.
