It has long been known that human breathing is altered during listening and speaking compared to rest: during speaking, inhalation depth is adjusted to the air volume required for the upcoming utterance. During listening, inhalation is temporally aligned to inhalation of the speaker. While evidence for the former is relatively strong, it is virtually absent for the latter. We address both phenomena using recordings of speech envelope and respiration in 30 participants during 14 min of speaking and listening to one's own speech. First, we show that inhalation depth is positively correlated with the total power of the speech envelope in the following utterance. Second, we provide evidence that inhalation during listening to one's own speech is significantly more likely at time points of inhalation during speaking. These findings are compatible with models that postulate alignment of internal forward models of interlocutors with the aim to facilitate communication.
长期以来，人们一直知道，与休息时相比，人类在听和说的过程中呼吸会发生变化：在说话时，吸气深度会根据即将发出的话语所需的空气量进行调整。在聆听时，吸气在时间上与说话者的吸气同步。虽然前者的证据相对充分，但后者几乎没有证据。我们通过记录30名参与者在14分钟的说话和听自己声音过程中的语音包络和呼吸情况，来研究这两种现象。首先，我们表明吸气深度与后续话语中语音包络的总功率呈正相关。其次，我们提供的证据表明，在听自己说话时，在说话时吸气的时间点更有可能出现吸气。这些发现与假设对话者内部前向模型对齐以促进交流的模型相一致。
