部分湘语存在一些有规律的异读现象,如非清去字读阴去、非浊去字读阳去、非入声字读入声。异读的作用有:区分词义、区分词性和区别词的使用频度。考察这些异读发现,其实质是小称变调。湘语的小称变调来源于唐宋时期江西中部移民所带来的方言。 Part of the Xiang language there are some irregular phenomenon, such as non-clear to read yin and yang, non-turbid to read yang to go, into the voice into the sound. The role of different reading are: to distinguish the meaning of the word, the distinction between the use of words and the frequency of distinction. Investigate these differences found that its essence is a small nominal tone. The minor name of Xiang dialect comes from the dialect brought by immigrants from central Jiangxi in the Tang and Song dynasties.
