声调演变类型学视角下的凤庆俐侎彝语中升24调的平化

The Transformation of 24 Tone In Limi of Yi Language In Fengqing from the Perspective of Tone Evolution Typology

本文运用声学实验和统计分析的方法,对凤庆俐侎彝语中可能存在的24调平化现象进行论证与分析。结果表明:(1)中升24调的确是帮景寨中正在发生的声调演变现象,不可置否;(2)年龄的大小和声母的类型是影响凤庆俐侎彝语中升24调平化的两大显著性因素。同时,凤庆俐侎彝语中升调平化路径不同于已有的声调演变类型中升调的演变规律,是较为独特的声调演变现象。

By means of acoustic experiments and statistical analysis,this paper demonstrates and analyses the24-tone evolutiontendency in Fengqing Limi of Yi language.The results show that:(1)24-tone is indeed a tone evolution phenomenon taking place in Bangjingzhai,which can not be denied;(2)Age and the type of initial consonants are two significant factors affecting the evolutiontendency of the tone in Limi.At the same time,the evolutionary path of 24-tone in Fengqing Limi is different from the evolutionary law of the tone evolutionary types,and it is a relatively unique tone evolutionary phenomenon.
