语气词的功能与韵律特征实验研究——以湖南城步方言典型语气词为例

An Experimental Study on the Functions and Prosodic Features of Modal Particles—A Case Study of Typical Modal Particles in the Chengbu Dialect of Hunan

摘要: 城步方言属湘语娄邵片。其语气词系统具有丰富的语用功能和较为鲜明的韵律特征，但相关实验语音研究仍相对不足。本文选取城步儒林话中的/man/、/və/、/tɕia/三个典型语气词作为研究对象，结合田野调查与实验语音学方法，在最小对立语境中采集语音数据，使用Praat提取基频(F0)、时长、音强等声学参数，并结合统计分析探讨不同语气词的韵律实现特点。本文观察到，不同语气词在不同功能条件下呈现出不同的声学参数变化趋势：/man/的差异主要表现为基频变化，/və/的情感表达更多依赖时长差异，/tɕia/的句法位置对立则体现为基频、时长和音强的综合作用。研究进一步表明，不同语气词并不存在统一的韵律表达模式，而是依据不同语用功能形成差异化的韵律参数组合；句法位置与语用功能之间存在较稳定的对应关系，并共同影响语气词的韵律实现。本文丰富了湘语语气词实验语音研究的个案材料，为理解汉语方言语气词的韵律实现机制以及句法、语用与韵律之间的互动关系提供了新的实验依据。

Abstract: The Chengbu dialect belongs to the Lou-Shao subgroup of Xiang Chinese. Its modal particle system exhibits rich pragmatic functions and distinctive prosodic characteristics, yet experimental phonetic studies on this dialect remain limited. This study investigates three representative modal particles in the Rulin variety of the Chengbu dialect, namely /man/, /və/, and /tɕia/. Combining fieldwork with experimental phonetics, speech data were collected under minimal contrastive contexts. Acoustic parameters, including fundamental frequency (F0), duration, and intensity, were extracted using Praat and subjected to statistical analysis to examine the prosodic realization of these modal particles. The results show that different modal particles rely on different prosodic cues to distinguish their pragmatic functions. Specifically, the functional contrast of /man/ is primarily realized through variations in fundamental frequency, the expressive functions of /və/ are mainly reflected by duration differences, while the contrast between the medial and sentence-final positions of /tɕia/ is characterized by the combined effects of fundamental frequency, duration, and intensity. The findings further indicate that there is no unified prosodic pattern for the realization of Chinese dialectal modal particles. Instead, different modal particles employ distinct combinations of prosodic parameters according to their pragmatic functions. Moreover, a relatively stable correspondence exists between syntactic position and pragmatic function, which jointly shapes the prosodic realization of modal particles. This study enriches the experimental phonetic description of modal particles in Xiang Chinese and provides new empirical evidence for understanding the prosodic realization of Chinese dialectal modal particles as well as the interaction among syntax, pragmatics, and prosody.
