The impact that vowels have on the variation across voice range profiles (VRPs) is studied along with three factors: fundamental frequency, singer's gender, and laryngeal vibratory mechanism used to sing.
VRPs of 21 advanced singers were established by recording, in separate takes, vocal productions using laryngeal vibratory mechanisms M1 and M2 for /a/, /i/, and /o/. Recordings were focused on the range C3-C5, where most singers can sing in either M1 or M2. It allows to compare the singer's dynamics in M1 versus M2 while holding other variables constant.
The vowel has an influence on the upper limit of singers' VRPs when they use M1 but not when they use M2, independently of the singer's gender and the fundamental frequency.
The laryngeal vibratory mechanisms allow one to explain the nonconsensual results observed in the literature about the influence of vowels on the VRP. A simulation shows that the different influence of vowels on the VRP partially results from the different open quotient values that can be observed in M1 and in M2.
研究在三个因素（基频、歌手性别和用于歌唱的声门振动机制）的影响下，母音对音域范围分布（VRP）变化的影响。
通过分别录制使用声门振动机制 M1 和 M2 发出的/a/、/i/和/o/音，为 21 名高级歌手建立了 VRPs。录制集中在 C3-C5 范围内，大多数歌手可以在 M1 或 M2 中演唱。这使得我们可以在保持其他变量不变的情况下，比较歌手在 M1 与 M2 中发声的动态。
当歌手使用 M1 时，母音会影响其 VRPs 的上限，但当他们使用 M2 时则不会，这与歌手的性别和基频无关。
声门振动机制可以解释文献中观察到的关于母音对 VRP 影响的不一致结果。模拟表明，母音对 VRP 的不同影响部分源于在 M1 和 M2 中可以观察到的不同开口商值。
