Taixing Lingua franca is based on the Taixing dialect for communication between people from different dialects. It is a contact-based variation with its own unique phonetic features. In this study, the author makes phonetic investigations in the Taixing district within the Tong-tai area. Holding the empirical attitude and focusing on the phonological “inheritance” and “transmission”, the author describes and analyzes the initial, final and tonal systems of the phonological features of Taixing Lingua franca. She also compares the Taixing Lingua franca with Xuzhou Putonghua and Shanghai Putonghua. It shows that in Taixing Lingua franca the probability of inheritance is higher than that of transmission in general. The more the speakers contact with Putonghua, the stronger the transmission will be. Besides, the direction of transformation is towards the literary pronunciation. There might be some learning behavior during communications, but generally it is spontaneous and unconscious behavior. This thesis consists of six parts: they are introduction, the sound system of the Taixing dialect, the initial system and its features of Taixing Lingua franca, the final system and its features of Taixing Lingua franca, the tonal system and its features of Taixing Lingua franca, and the conclusion.

“泰興方言的交際語變體”是以泰興方言為基礎，以進行不同方言人員之 間交際為目的，具有自身獨特語音系統特徵的接觸變體。本文主要採用田野調 查的研究方法，長時間、多輪次談話錄音的調查方式，在泰興地區（通泰方言 區）進行語音調查，以採擷第一手泰興方言交際語變體的語料。本文圍繞“沿 用”與“轉化”對泰興方言交際語變體的語音面貌——泰興方言交際語變體的 聲母、韻母及聲調系統及語音特徵等方面進行描寫、歸納、分析，並將其與徐 州口音普通話、上海話-普通話中介音的語音特徵進行比較分析。本文發現，泰 興方言的交際語變體中，聲、韻、調都存在大量原泰興方言的“沿用”以及與 全國通用語的“轉化”，相較“轉化”“沿用”頻率更高，總體是向書面語方面 轉化；發音人與全國通用語接觸越多，轉化越強；其形成過程中或有學習行 為，但本質上還是自發的無意識行為；相較聲母與韻母系統，原方言的聲調系 統是泰興方言交際語變體的發音人最難跳出的，也更能代表泰興方言交際語變 體的特點。 全文由緒論、泰興方言概況、泰興方言交際語變體的聲母系統及其語音特 徵、泰興方言交際語變體的韻母系統及其語音特徵、泰興方言交際語變體的聲 調系統及其語音特徵、結語等六部分組成。
