Research on Checked Tone in Lingchuan Dialect

This paper selects normal checked characters and makes a comprehensive analysis of checked tone merging in Lingchuan dialect from rhyme, initial consonants and tone. In terms of rhyme, geng rhyme’s merging speed is fastest and shen rhyme is slowest. As for ancient consonants, nasal has the fastest speed, and voiced initial has the slowest speed. Judging from the attribution of the tones, the voiced and nasal initial checked characters are majorly classified into the departing tone, while the voiceless initial checked characters are attributed to four tone categories. The merging in Lingchuan dialect mostly follows the rules of mandarin, but from the perspective of the quantity, there are a few differences between Lingchuan dialect and Mandarin.
