An Analysis Of Tones In Yangzhou Dialect

dialect based on acoustic data. There are four parts in this study. First, 1 give a brief introduction to the initials and finals of Yangzhou dialect and review the previous studies on the tones of Yangzhou dialect. In the second part, with the help of MiniSpeechLab software I analyze the experimental data on tone sandhi in Yangzhou -dialect and make a phonological analysis. The experiment was carried out in three aspects: tones in citation form, tone sandhi in disyllabic sequences and tone sandbi in trisyllabic sequences. In Yangzhou dialect, there are five citation tones: Ti (31), T2 (35), 13 (42), T4 (55) and 15 (i). The main tone sandbi phenomena are represented as follows: Then, 1 analyze tone sandhi in Yangzhou dialect within the framework of Optimality Theory. It shows that 01 can provide a simple and correct analysis of tone sandhi in Yangzhou dialect. In the third part. I first study the experimental data on neutral tone in Yangzhou dialect with the help of MiniSpeechLab software. The experiment was carried out in two aspects: neutral tone in disyllabic sequences and neutral tone in irisyllabic sequences. In disyllabic and trisyllabic sequences, the pitch value of neutral tone in Yangzhou dialect is influenced by the preceding tone. The starting point of neutral tone is in coarticulation with the ending point of the preceding stressed tone. The ending point of neutral tone is determined by the tonal category of the preceding one. In trisyllabic sequences, the first stressed tone will follow tone sandhi processes first. I analyze neutral tone in Yangzhou dialect within the framework of Autosegmental Phonology. It shows that Autosegmental Phonology can give a correct analysis of neutral tone in Yangzhou dialect The last part of the thesis is a conclusion.
