在声调音系学中，无界的环绕过程是常见的，但在音段音系学中却很少见。然后，它认为这种类型不对称的最好特征是假设声调在计算上比音段音系学更复杂。这种不对称性的证据是基于无界音调平坦的证明，但它也表明了‘酸葡萄’和声病理是如何无界的周围环境。本文认为，这种过程并不是弱确定性的，这与以往的音段音位类型学工作形成了鲜明对比。认为弱决定论是音段音系的界限，而不是声调音系的界限，从而捕捉到了类型的不对称性。文中还讨论了为什么这种解释优于最优性理论的解释。
This paper establishes that unbounded circumambient processes, phonological processes for which crucial information in the environment may appear unboundedly far away on both sides of a target, are common in tonal phonology, but rare in segmental phonology. It then argues that this typological asymmetry is best characterised by positing that tone is more computationally complex than segmental phonology. The evidence for the asymmetry is based around attestations of unbounded tonal plateauing, but it is also shown how the ‘sour-grapes’ harmony pathology is unbounded circumambient. The paper argues that such processes are not weakly deterministic, which contrasts with previous typological work on segmental phonology. Positing that weak determinism bounds segmental phonology but not tonal phonology thus captures the typological asymmetry. It is also discussed why this explanation is superior to any offered by Optimality Theory.
