Theoretic investigations of the "source-filter" model have indicated a pronounced acoustic interaction of glottal source and vocal tract. Empirical investigations of formant pattern variations apart from changes in vowel identity have demonstrated a direct relationship between the fundamental frequency and the patterns. As a consequence of both findings, independence of phonation and articulation may be limited in the speech process. Within the present study, possible interdependence of phonation and phoneme was investigated: vocal fold vibrations and larynx position for vocalizations of different vowels in a healthy man and woman were examined by high-speed light-intensified digital imaging. We found 1) different movements of the vocal folds for vocalizations of different vowel identities within one speaker and at similar fundamental frequency, and 2) constant larynx position within vocalization of one vowel identity, but different positions for vocalizations of different vowel identities. A possible relationship between the vocal fold vibrations and the phoneme is discussed.
“源-滤波器”模型的理论研究表明声门源和声道之间存在显著的声学相互作用。除元音特性变化外，对共振峰模式变化的实证研究表明基频与这些模式之间存在直接关系。基于这两个发现，发声和发音的独立性在言语过程中可能受到限制。在本研究中，对发声和音素之间可能的相互依存关系进行了调查：通过高速光增强数字成像检查了一名健康男性和女性在发出不同元音时的声带振动和喉部位置。我们发现：1）在同一说话者发出具有相似基频的不同元音时，声带运动不同；2）在发出同一元音时喉部位置恒定，但发出不同元音时喉部位置不同。文中还讨论了声带振动与音素之间可能存在的关系。
