Durational aspects of turn-taking in spontaneous face-to-face and telephone dialogues

Abstract

On the basis of two-speaker spontaneous conversations, it is shown that the distributions of both pauses and speech-overlaps of telephone and face-to-face dialogues have different statistical properties. Pauses in a face-to-face dialogue last up to 4 times longer than pauses in telephone conversations in functionally comparable conditions. There is a high correlation (0.88 or larger) between the average pause duration for the two speakers across face-to-face dialogues and telephone dialogues. The data provided form a first quantitative analysis of the complex turn-taking mechanism evidenced in the dialogues available in the 9-million-word Spoken Dutch Corpus. © Springer-Verlag Berlin Heidelberg 2004.
