言语产生中音节频率效应的认知机制:跨语言视角

The cognitive mechanism of syllable frequency effects in speech production:A cross-language perspective

在口语词汇产生过程中,音节频率效应(syllable frequency effect)指的是高频音节相对于低频音节的加工优势。综述了言语产生过程中音节频率效应的表现形式和理论基础,从影响因素、发生阶段和神经机制等角度阐述了印欧语系和汉语中音节频率效应的跨语言差异。基于口语产生的理论模型和合适单元假说,结合不同语言的固有特性,分析了音节频率效应存在跨语言差异的原因,提出了一个有关汉语口语词汇产生中音节作用机制的模型,为音节在汉语和字母语言口语产生过程中的作用提供了新的视角。未来应进一步探究音节频率的两种测量方式对音节频率效应产生影响的具体机制,加强对汉语口语词汇产生中音节频率效应的考察,利用多种实验技术和范式深入探讨言语产生过程中音节加工的跨语言差异。

In speech production,the syllable frequency effect refers to the processing advantage of high frequency syllables over low frequency syllables.Features and theories of the syllable frequency effect in speech production of Chinese and Indo-European languages are summarized,and the cross-language differences of the syllable frequency effect are discussed from the perspectives of its main contributors,processing stages,and neural mechanisms.Based on the speech production model and proximate units principle,as well as considering the inherent properties of different languages,we analyse the potential causes for the cross-language differences in syllable frequency effects and propose a model to clarify the mechanism of syllable processing in Chinese speech production,which provides a new perspective on different roles of syllables in speech production of Chinese or alphabetic languages.Future studies should distinguish the effects of token syllable frequency and type syllable frequency,and focus on Chinese syllable frequency effects through a variety of techniques and paradigms,to further explore the cognitive mechanism and cross-language differences of syllable processing in spoken word production.
