In recent years there has been increasing recognition of the vital role of intonation in speech communication. While contemporary models represent intonation—the tune—and the text that bears it on separate autonomous tiers, this paper distils previously unconnected findings across diverse languages that point to important interactions between these two tiers. These interactions often involve vowels, which, given their rich harmonic structure, lend themselves particularly well to the transmission of pitch. Existing vowels can be lengthened, new vowels can be inserted and loss of their voicing can be blocked. The negotiation between tune and text ensures that pragmatic information is accurately transmitted and possibly plays a role in the typology of phonological systems.

近年来，人们越来越意识到语调在语音交流中的重要作用。尽管当代模型代表了语调（曲调）以及承载在单独的自治层上的文本，但本文还是将先前未关联的发现分散到了多种语言中，指出了这两个层之间的重要交互作用。这些相互作用通常涉及元音，由于其丰富的谐波结构，它们特别适合于音高的传递。可以延长现有的元音，可以插入新的元音，并且可以阻止发声失败。音调和文本之间的协商确保了实用信息的准确传输，并可能在语音系统的类型学中发挥作用。
