Breathing is variable but also highly individual. Since the 1980s, evidence of a ventilatory personality has been observed in different physiological studies. This original term refers to within-speaker consistency in breathing characteristics across days or even years. Speech breathing is a specific way to control ventilation while supporting speech planning and phonation constraints. It is highly variable between speakers but also for the same speaker, depending on utterance properties, bodily actions, and the context of an interaction. Can we yet still observe consistency over time in speakers’ breathing profiles despite these variations? We addressed this question by analyzing the breathing profiles of 25 native speakers of German performing a narrative task on 2 days under different limb movement conditions. The individuality of breathing profiles over conditions and days was assessed by adopting methods used in physiological studies that investigated a ventilatory personality. Our results suggest that speaker-specific breathing profiles in a narrative task are maintained over days and that they stay consistent despite light physical activity. These results are discussed with a focus on better understanding what speech breathing individuality is, how it can be assessed, and the types of research perspectives that this concept opens up.

言语呼吸：随时间和肢体运动变化，但因人而异

呼吸是可变的，但也是高度个体化的。自 1980 年代以来，通风人格的证据已在不同的生理研究中观察到。这个原始术语是指在数天甚至数年内，说话者内部呼吸特征的一致性。语音呼吸是一种在支持语音规划和发声约束的同时控制通气的特定方式。它在说话者之间是高度可变的，但对于同一说话者来说也是如此，这取决于话语属性、身体动作和交互的上下文。尽管存在这些变化，我们还能观察到说话者呼吸曲线随时间推移的一致性吗？我们通过分析 25 名以德语为母语的人在 2 天内在不同肢体运动条件下执行叙事任务的呼吸曲线来解决这个问题。通过采用调查通气特性的生理研究中使用的方法来评估不同条件和天数的呼吸曲线的个性。我们的研究结果表明，叙事任务中特定于说话者的呼吸曲线可以保持数天，并且尽管有轻微的体力活动，它们仍保持一致。讨论这些结果的重点是更好地理解什么是语音呼吸个性，如何评估它，以及这一概念开辟的研究视角的类型。
