记录了10对（20名受试者）在安静呼吸、大声朗读、自发独白、脚本对话和自发谈话时的呼吸运动。吸气、呼气和总周期持续时间的定时测量用于比较安静呼吸、听力和说话时的呼吸功能。通过对对话对象呼吸运动的相互关联分析，得出了对话同步性的指标。吸气持续时间是区分安静呼吸和言语呼吸的最一致和最敏感的指标。在脚本对话和自发对话条件下，呼吸运动学在听更接近语音的过程中发生了变化，并且在轮到语音开始的预期中观察到系统性变化。当呼吸周期直接围绕旋转变化并同时产生声音事件时，会话伙伴的运动信号具有强相关性。这些结果是在会话互动和言语运动准备方面的类似发现的背景下讨论的。
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.
