This investigation was designed to test the hypothesis that voice onset time (VOT) varies as a function of lung volume. Recordings were made of five men as they repeated a phrase containing stressed /pi/ syllables, beginning at total lung capacity and ending at residual volume. VOT was found to be longer at high lung volumes and shorter at low lung volumes in most cases. This finding points out the need to take lung volume into account when using VOT as an index of laryngeal behavior in both healthy individuals and those with speech disorders.
本研究旨在检验声门起始时间（VOT）随肺容量变化的假设。对五名男性进行了录音，他们重复一个包含重读/pi/音节的短语，从肺总量开始，到残气量结束。在大多数情况下，发现高肺容量时VOT较长，低肺容量时VOT较短。这一发现指出，在将VOT用作健康个体和言语障碍患者喉部行为指标时，有必要考虑肺容量。
