本研究探讨了声调变化对正常喉（NL）和上级食管（SE）说话者嗓音起始时间（VOT）的影响。以8名母语为普通话的NL人和7名SE人为研究对象，测量了他们在四个声调水平上发出的音节/p（h）a/、/t（h）a/和/k（h）a/的VOT值。结果表明，普通话声调与显着不同的VOT值为NL的发言者，其中高降调与显着较短的VOT值比中升调和降升调。至于扬声器组，SE扬声器显示出显着较短的VOT值比NL扬声器在所有的音调水平。这可能与他们使用咽食管（PE）段作为另一个声源有关。与使用声带振动的NL扬声器相比，SE扬声器似乎需要更短的时间来开始PE段振动。
The present study investigated the effect of tonal changes on voice onset time (VOT) between normal laryngeal (NL) and superior esophageal (SE) speakers of Mandarin Chinese. VOT values were measured from the syllables /p(h)a/, /t(h)a/, and /k(h)a/ produced at four tone levels by eight NL and seven SE speakers who were native speakers of Mandarin. Results indicated that Mandarin tones were associated with significantly different VOT values for NL speakers, in which high-falling tone was associated with significantly shorter VOT values than mid-rising tone and falling-rising tone. Regarding speaker group, SE speakers showed significantly shorter VOT values than NL speakers across all tone levels. This may be related to their use of pharyngoesophageal (PE) segment as another sound source. SE speakers appear to take a shorter time to start PE segment vibration compared to NL speakers using the vocal folds for vibration.
