Analyzing Nanjing Tones and Sandhi: Statistical Modelling Methods

In this study, we used growth curve analysis to model the surface f0 contours of the sandhi tones, and we also modelled the underlying pitch target of sandhi tones and their corresponding citation tones in Nanjing Chinese. The underlying pitch targets of reported sandhi tones showed neutralization with reported base tones in most cases, but the surface f0 contours of each pair were not neutralized. Our results provided acoustic evidence for the debate over the existence of some tone sandhi rules in Nanjing Chinese based on impressionistic data. Finally, transcription modification of some monosyllabic Nanjing Chinese tones was recommended based on the transformation of the results of the statistical modelling of the acoustic data
