Confusion exists about the effect of mass and size of the vocal folds on fundamental frequency (F0) of phonation. In particular, greater vocal fold thickness is often assumed to be associated with lower F0. The purpose here is to show that such a relationship does not exist and that F0 should be conceptualized with quantities other than mass (i.e., length and tissue stress).
Arguments are made on the basis of fundamental laws of mechanics (point-mass vs. distributed mass).
In speech science, phonetics, and animal vocalization disciplines, instruction should shift away from point-mass descriptions of vocal fold tissue and toward an understanding of mode frequencies in an elastic continuum.
关于声带的质量和大小对基频(F0)的影响,存在混淆。特别是,通常认为更大的声带厚度与更低的 F0 相关。这里的目的是表明这种关系并不存在,并且 F0 应该用质量以外的量来概念化(即长度和组织应力)。
基于力学的基本定律(质点与分布质量)进行论证。
在语音科学、语音学和动物发声学科中,应该从对声带组织的质点描述转向对弹性连续体中模态频率的理解。
