语音区别特征的不相似度研究
A STUDY OF DISSIMILARITY IN DISTINCTIVE FEATURES
-
摘要: 因为语音一级是代表音韵分类的最后阶段,本研究企图弄清从Chomsky和Halle系统中选出的某些区别特征的知觉特色及其适当性。本文融合了心理物理的倾向性与记忆技巧,以绕过用两对最小区别对之间的不相似度的强迫选择判决带来的言语多余度问题。本研究还设计得用来证实Stewart和Barach22从前所做的另一项研究的某些方面。结果指出,某些区别特征比另一些区别特征更突出,并且分层结构似乎是合理的。结果还表明,区别特征的知觉权重是不同的,并且在性质上也不是严格二进制的。Abstract: Since the phonetic level represents the final stages of the higher-order phonologral level, the present study sought to ascertain the perceptual saliency of certain selected distinctive features from the Chomsky and Halle (1968) system and their appropriateness. The study combined a psychophysieal orientation and a memory strategy in order to circumvent the problem of speech redundancy with a forced-choice decision of dissimilarity between two-pairs of minimally-distinct dyads. In addition, the investigation was designed to validate certain aspects of an earlier study by Stewart and Barach (1978). The results indicated that certain features are more salient than others and a hierarchical structure is plausible. The study appears to show that distinctive features do not possess equal perceptual weightings, and are not strictly binary in nature.
