Entrainment in Multi-Party Spoken Dialogues at Multiple Linguistic Levels

Linguistic entrainment, the phenomena whereby dialogue partners speak more similarly to each other in a variety of dimensions, is key to the success and naturalness of interactions. While there is considerable evidence for both lexical and acoustic-prosodic entrainment, little work has been conducted to investigate the relationship between these two different modalities using the same measures in the same dialogues, specifically in multi-party dialogue. In this paper, we measure lexical and acoustic-prosodic entrainment for multi-party teams to explore whether entrainment occurs at multiple levels during conversation and to understand the relationship between these two modalities.
