Voice modulatory cues such as variations in fundamental frequency, duration and pauses are key factors for structuring vocal signals in human speech and vocal communication in other tetrapods. Voice modulation physiology is highly similar in humans and other tetrapods due to shared ancestry and shared functional pressures for efficient communication. This has led to similarly structured vocalizations across humans and other tetrapods. Nonetheless, in their details, structural characteristics may vary across species and languages. Because data concerning voice modulation in non-human tetrapod vocal production and especially perception are relatively scarce compared to human vocal production and perception, this review focuses on voice modulatory cues used for speech segmentation across human languages, highlighting comparative data where available. Cues that are used similarly across many languages may help indicate which cues may result from physiological or basic cognitive constraints, and which cues may be employed more flexibly and are shaped by cultural evolution. This suggests promising candidates for future investigation of cues to structure in non-human tetrapod vocalizations. This article is part of the theme issue 'Voice modulation: from origin and mechanism to social impact (Part I)'.
语音调节线索，如基频、时长和停顿的变化，是人类言语和其他四足动物声音交流中构建语音信号的关键因素。由于共同的祖先和高效交流的共同功能压力，人类和其他四足动物的语音调节生理学非常相似。这导致了人类和其他四足动物之间具有相似结构的发声。尽管如此，在细节上，结构特征可能因物种和语言而异。由于与人类言语产生和感知相比，关于非人类四足动物声音产生和感知中的语音调节的数据相对较少，因此本综述重点关注跨人类语言使用的语音调节线索，突出显示现有比较数据。在许多语言中被相似使用的线索可能有助于表明哪些线索可能是由生理或基本认知限制引起的，哪些线索可能更灵活地被使用并受到文化进化的影响。这为未来研究非人类四足动物声音结构的线索提供了有希望的候选对象。本文是主题为“语音调节：从起源和机制到社会影响（第一部分）”的一部分。
