连读变调的方向性及串行优选论下的解决方案

Directionality of Tone Sandhi and the Account of Harmonic Serialism

连读变调的方向性是指作用在两字组的连读变调规律,在应用于三字组或三字以上结构时,其运用顺序或方向会出现不统一的现象。最为典型的案例就是天津方言三字组的连读变调。变调方向上的差异实际上是对标记性结构修复模式上的差异,而这种差异是声调稳定性与声调异化制约条件相互作用的结果。串行优选论弥补了经典优选论的不足,从而能够描述和分析天津方言三字组的连读变调。

Directionality of tone sandhi is that the applying orders or directions of the tone sandhi rules which are applied in disyllabic patterns are not consistent in the condition that such rules are applied in trisyllabic or multisyllabic patterns.The typical case is the trisyllabic sandhi patterns of Tianjin dialect.The directionality is in nature a difference in repair strategies which is determined by the interaction between tonal stability and obligatory contour principles.Directionality of tone sandhi of Tianjin dialect can be analyzed and accounted in the framework of harmonic serialism which remedies the defects of classical OT.
