In phonetics, a term sometimes used for an anatomical region within which relatively large variations in articulation have no or minor acoustic consequences. However, a small shift outside of this zone will produce a large acoustic change. It is argued that articulation is evolutionarily organized to make maximum use of the vocal tract’s ability to produce such changes, which are thus critical in the development of phonological distinctiveness. The notion is central to the quantal theory of speech proposed by US phonetician Kenneth N. Stevens.

 

语音学有时用来指一个发音区,在这个区域内次发音动作的变化不会造成可察觉的听觉变化,但超出这个区域的细小变化就会产生重大声学变化。按这种理论,发音过程是人类进化的结果,能最大限度地利用声道产生这类变化的能力,这类变化因此对音系区别性的发展至关重要。这个概念是美国语音学家K. N.史蒂文斯提出的语音量子理论中的重要概念。
