【摘要】 声调范畴化感知是语音学和认知神经科学等领域关注的焦点。前人研究指出，调型相异的声调间的感知模式通常是范畴感知，调型相同的声调间的感知模式则是连续感知，然而有关声调范畴感知和连续感知的成因一直没有得到解决。本文以黔东苗语新合话的三个升调为例探讨这一问题。研究发现，无论调型异同，当声调间的基频斜率存在显著性差异时，感知结果就会表现出范畴感知的特性；当声调间的基频斜率无显著性差异时，感知结果就会表现出连续感知的特性。这一发现解决了声调感知理论中的一个根本问题，即基频斜率是导致声调范畴感知和连续感知区分的一项决定性因素。在此基础上，本文提出声调范畴化感知是个连续统的观点。更多还原

【Abstract】 The categorization of tone perception has attracted extensive attention in the fields of phonetics and cognitive neuroscience. Previous studies have pointed out that the perception is categorical when the tones have different shapes, while continuous when the tones have the same shape with different pitch levels. However, it has been unresolved concerning the causes of categorical perception and continuous perception. Taking the three rising tones of Hmu(Xinhe Variety) as an example, this study reveals that the perception is categorical when there is significant difference in F0 slope among the tones no matter tone shapes are the same or different, while continuous when there is no significant difference in F0 slope among the tones. This finding solves a fundamental problem in the theory of tone perception, i.e., F0 slope leads to the distinction between categorical and continuous perception. On this basis, the present study proposes that there is a continuum regarding the categorization of tone perception.更多还原
