Vocalic

元音性

 

One of the major class features of sound set up by generative phonologists in their distinctive feature theory of phonology, its opposite being non-vocalic. Vocalic sounds may be defined articulatorily or acoustically in this approach: they are sounds where there is a free passage of air through the vocal tract, the most radical constriction in the oral cavity not exceeding that found in [i] and [u], and the vocal folds being positioned so as to allow spontaneous voicing; acoustically, there is a sharply defined formant structure. Non-vocalic sounds lack one or other of these conditions.

 

生成音系學在音系學的區別特征理論中確立的主要類特征之一,與非元音性對立。這種理論中元音性語音可從發音和聲學兩方面定義為:聲道內空氣流通自由,口腔內的最大收縮不超過[i]和[u]音的收縮,聲帶的位置允許自發帶聲;聲學上有一個明顯界定的共振峰結構。非元音性語音不完全滿足上述條件。
