This study explores the relationship between inhalation amplitude and turn management in four approximately 20 minute long spontaneous multiparty conversations in Estonian. The main focus of interest is whether inhalation amplitude is greater before turn onset than in the following inhalations within the same speaking turn. The results show that inhalations directly before turn onset are greater in amplitude than those later in the turn. The difference seems to be realized by ending the inhalation at a greater lung volume value, whereas the initial lung volume before inhalation onset remains roughly the same across a single turn. The findings suggest that the increased inhalation amplitude could function as a cue for claiming the conversational floor.
