The taking of turns to speak is an intrinsic property of conversation. It is therefore expected that models of turn-taking, providing a prior distribution over conversational form, can usefully reduce the perplexity of what is observed and processed in real-time spoken dialogue systems. We propose a conversation-independent single-port model of multi-party turn-taking, one which allows conversants to undertake independent actions but to condition them on the past behavior of all participants. The model is shown to generally out perform an existing multi-port model on a measure of perplexity over subsequently observed speech activity. We quantify the effect of history truncation and the success of predicting distant conversational futures, and argue that the framework is sufﬁciently accessible and has signiﬁcant potential to usefully inform thedesignandbehaviorofspokendialoguesystems.
