Cognitive theories of dialogue hold that en- trainment, the automatic alignment between dialogue partners at many levels of linguistic representation, is key to facilitating both pro- duction and comprehension in dialogue. In this paper we examine novel types of entrain- ment in two corpora—Switchboard and the Columbia Games corpus. We examine en- trainment in use of high-frequency words (the most common words in the corpus), and its as- sociation with dialogue naturalness and flow, as well as with task success. Our results show that such entrainment is predictive of the per- ceived naturalness of dialogues and is signifi- cantly correlated with task success; in overall interaction flow, higher degrees of entrainment are associated with more overlaps and fewer interruptions.
