Lung volumes during reading and associated factors such as speech intensity and linguistic influences were studied in six healthy young women over 7 to 10 sessions, using respiratory inductive plethysmography. Intrasubject variability of lung volumes over the sessions was almost as great as the intersubject variability. Some of the intrasubject variability was associated with natural variations of speech intensity within a "comfortable loudness" range. The lung volume variability during reading is contrasted with high degrees of both inter- and intrasubject consistency in the location of inspirations, which occurred almost exclusively at grammatically appropriate places in the texts (paragraph, sentence, clause, and phrase boundaries). Within each reading passage, lung volumes were significantly increased for (a) louder utterances, (b) inspirations at sentence and paragraph boundaries compared to inspirations at other locations within sentences, (c) longer utterances compared to shorter utterances, and (d) initial breaths compared to final breaths. The implications of these findings for the neural control of breathing during speech are considered.
在7至10次会话期间，使用呼吸感应体积描记法对6名健康年轻女性阅读时的肺容量以及诸如语音强度和语言影响等相关因素进行了研究。各次会话期间肺容量的受试者内变异性几乎与受试者间变异性一样大。受试者内的一些变异性与“舒适响度”范围内语音强度的自然变化有关。阅读期间的肺容量变异性与吸气位置的高度受试者间和受试者内一致性形成对比，吸气几乎只发生在文本中语法合适的位置（段落、句子、从句和短语边界）。在每篇阅读文章中，肺容量在以下情况时显著增加：(a) 声音更大的发声；(b) 与句子内其他位置的吸气相比，句子和段落边界处的吸气；(c) 较长发声与较短发声相比；(d) 初始呼吸与最终呼吸相比。本文考虑了这些发现对言语过程中呼吸神经控制的意义。
