According to experience in voice therapy and singing pedagogy, breathing habits can be used to modify phonation, although this relationship has never been experimentally demonstrated. In the present investigation we examine if lung volume affects phonation. Twenty-four untrained subjects phonated at different pitches and degrees of vocal loudness at different lung volumes. Mean subglottal pressure was measured and voice source characteristics were analyzed by inverse filtering. The main results were that with decreasing lung volume, the closed quotient increased, while subglottal pressure, peak-to-peak flow amplitude, and glottal leakage tended to decrease. In addition, some estimates of the amount of the glottal adduction force component were examined. Possible explanations of the findings are discussed.
根据语音治疗和声乐教学的经验，呼吸习惯可用于改变发声，尽管这种关系从未得到实验证明。在本研究中，我们研究肺容量是否会影响发声。24名未经训练的受试者在不同肺容量下以不同音高和不同发声响度进行发声。测量了平均声门下压力，并通过逆滤波分析了声源特性。主要结果是，随着肺容量的减小，声门闭合商增加，而声门下压力、峰-峰流量幅度和声门漏气倾向于减小。此外，还研究了声门内收力分量大小的一些估计值。对这些发现的可能解释进行了讨论。
