This paper presents evidence that tone well-formedness patterns share a property of melody-locality , and shows how patterns with this property can be learned. Essentially, a melody-local pattern is one in which constraints over an autosegmental melody operate independently of constraints over the string of tone-bearing units. This includes a range of local tone patterns, long-distance tone-patterns, and their interactions. These results are obtained from the perspective of formal language theory and grammatical inference, which focus on the structural properties of patterns, but the implications extend to other learning frameworks. In particular, a melody-local learner can induce attested tone patterns that cannot be learned by the tier projection learners that have formed the basis of work on learning long-distance phonology. Thus, melody-local learning is a necessary property for learning tone. It is also shown how melody-local learners are more restrictive than learning directly over autosegmental representations.

旋律学习和长距离音调

这篇论文提出了证据表明，音调结构良好的模式共享旋律局部性的属性，并展示了如何学习具有此属性的模式。本质上，旋律本地模式是这样一种模式，其中对自动分段旋律的约束独立于对音调承载单元串的约束运行。这包括一系列本地音调模式、长距离音调模式及其相互作用。这些结果是从形式语言理论和语法推理的角度获得的，它们侧重于模式的结构特性，但其含义扩展到其他学习框架。特别是，旋律本地学习者可以诱发已证明的音调模式，而这些音调模式是构成远程音韵学习工作基础的分层投影学习者无法学习的。因此，旋律本地学习是学习音调的必要属性。它还显示了旋律本地学习器如何比直接在自动分段表示上学习更具限制性。
