区别特征理论在音系学和语音学理论中都占有重要的地位,区别特征在描写跨语言和语言内部的音系现象方面表现出的解释力说明了特征所表达的语音自然类是有普遍意义的。近年来,语音学研究从语音产生和感知的角度为区别特征的语音学基础提供了有力的证据。在语音产生和感知的过程中,发音生理、物理声学和听觉感知三者之间存在着非线性的量子化关系,这种关系恰恰跟区别特征相对应。在连续语流中,与区别特征相关的声学信号常常发生变化,其影响因素包括语音单元所处的韵律位置、区别特征附加的增强动作和发音动作的重叠。听话人理解语音的过程就是从声学信号中提取区别特征、组合音段和构造词汇的过程。 The distinctive feature theory plays an important role in phonology and phonetics theory. The explanatory power of the distinguishing features in describing cross-language and phonological phenomena in language indicates that the natural class of speech expressed by the features is of universal significance of. In recent years, phonetic studies have provided strong evidence for distinguishing phonetic features of features from the perspective of speech production and perception. In the process of speech generation and perception, there exists a non-linear quantization relationship between phonological physiology, phonological acoustics and auditory perception, which exactly corresponds to the distinguishing features. In continuous speech, the acoustic signals related to distinguishing features often change, and the influencing factors include the prosodic position where the speech unit is located, the additional enhancement action of the distinctive feature and the overlap of pronunciation actions. Hearer’s understanding of speech is the process of extracting distinctive features, combining segments, and constructing words from acoustic signals.
