Respiratory movements were recorded from 10 dyads (20 subjects) during quiet breathing, reading aloud, spontaneous monologue, scripted dialog, and spontaneous conversation. Timing measures of inspiratory, expiratory, and total cycle duration were used to compare respiratory function during quiet breathing, listening, and speech. Cross-correlation analyses of the respiratory movements of conversational partners provided an index of conversational synchrony. Inspiratory duration was found to be the most consistent and sensitive measure for discriminating quiet breathing from speech breathing. In the scripted dialog and spontaneous conversation conditions, respiratory kinematics changed during listening to more closely resemble speech, and systematic changes were observed in anticipation of turn-taking speech onset. For the breathing cycles immediately surrounding turn changes and simultaneously produced vocal events, the kinematic signals of conversational partners were strongly correlated. Results are discussed in the context of similar findings concerning conversational interactions and motor preparation for speech.
在安静呼吸、大声朗读、自发独白、脚本对话和自发对话期间，记录了10对（20名受试者）的呼吸运动。使用吸气、呼气和总周期持续时间的计时测量来比较安静呼吸、倾听和说话时的呼吸功能。对对话伙伴的呼吸运动进行互相关分析，提供了对话同步性的指标。发现吸气持续时间是区分安静呼吸和言语呼吸最一致和最敏感的指标。在脚本对话和自发对话条件下，倾听时呼吸运动学发生变化，更类似于言语，并且在预期轮流发言开始时观察到系统变化。对于紧围绕轮次变化和同时产生的发声事件的呼吸周期，对话伙伴的运动学信号高度相关。在关于对话互动和言语运动准备的类似发现的背景下讨论了结果。
