Conversations require individuals to comprehend speech while preparing responses, with demands increasing significantly in noise or with more people involved. Here, we explore the impact of noise on turn-taking dynamics in triadic conversations. Ten groups of three young, normal-hearing participants engaged in conversations at two levels of 8-talker babble noise, with each group holding three conversations under noisy conditions and three in quiet. We extracted objective measures of turn-taking dynamics from the recorded speech and assessed subjective ratings of conversational difficulty. Conversations in noise were shorter, with reduced distance between participants, fewer overlaps-within, and fewer, more delayed, and variable floor transfers. The conversational dynamics in noise correlated with the subjective ratings. Overall, changes in turn-taking dynamics in triadic conversations in noise resemble those in dyads, reflecting alterations in conversational flow and engagement.
