The three years of my research have yielded satisfactory results. The sound change mechanism has been explored through statistical analysis using data from both Mandarin and other languages. Five papers have been published in different international journals, all Scopus-indexed. The study has proven that the frequency factor plays a complex role in sound change, and it is not as simple as either high-frequency or low-frequency words leading sound change. My study shows that (i) the most frequent words tend to be exceptions in sound change, and (ii) the frequency change factor is positively related to strengthening sound changes and negatively associated with weakening sound changes.
