A Study on Syllable Prolonging by Merging of the Modal Verb Yao in Pingjiang Gan Dialect of Hunan Province

湖南平江赣语情态动词“要”的声韵调在语流中通常省去,而时值和意义保留并合入到前音节里,致使其发音延长,形成省略合并型长音。实验语音分析显示,“要”的主要省合音变规律为:音节的主要元音发音明显加长,声调调值变为[原调值+4]。语言经济原则以及音系规则、韵律法则是省合长音产生的动因与机制,而“要”的半虚化属性是其得以生成的根本原因。

The modal verb yao in Pingjiang Gan Dialect of Hunan Province usually merges into the preceding syllable to form a prolonged one.The experimental phonetic analysis shows some rules of syllable prolonging by merging:the main vowels of the syllable are obviously lengthened,and the tone value changes into[original tone value+4].The motivation and mechanism of syllable prolonging are economic principle of language,phonological rules and rules of rhythm,but the fundamental reason is the grammaticalization of yao.
