“天津话连读变调之谜”可以归结为两大谜团:一是变调的方向性和规则施用的方式,二是去阴变调的特殊性。自变调之谜提出以来,各家有着不同的分析,对谜团的解释分别涉及经济性、变调复杂度、节律等因素,采用的理论框架包括经典生成音系学和优选论。基于管辖音系学声调理论的框架,通过对天津话的声调结构进行重新分析,可以得出结论:在明确了天津话的声调结构之后,通过对天津话连读变调中的OCP进行重新界定,并确立其与变调过程的交互作用,“天津话连读变调之谜”即可得以解开。 “Tianjin dialect read the mystery ” can be attributed to two mysteries: one is the direction of change and the rules of application, the second is to change the particularity of the yin and yang. Since the mystery was proposed, each has its own different analysis. The explanations of the mystery involve economic factors, complexity of change and rhythm respectively. The theoretical framework adopted includes classical phonology and preference theory. Based on the framework of tone theory of jurisdictional phonology, through the reanalysis of the tone structure of Tianjin dialect, we can conclude that after defining the tone structure of Tianjin dialect, by redefining the OCP in tone dialect of Tianjin dialect, And establish its interaction with the process of change, “Tianjin dialect read the mystery ” can be solved.
