Emotional voices attract considerable attention. A search on any browser using “emotional prosody” as a key phrase leads to more than a million entries. Such interest is evident in the scientific literature as well; readers are reminded in the introductory paragraphs of countless articles of the great importance of prosody and that listeners easily infer the emotional state of speakers through acoustic information. However, despite decades of research on this topic and important achievements, the mapping between acoustics and emotional states is still unclear. In this article, we chart the rich literature on emotional prosody for both newcomers to the field and researchers seeking updates. We also summarize problems revealed by a sample of the literature of the last decades and propose concrete research directions for addressing them, ultimately to satisfy the need for more mechanistic knowledge of emotional prosody.

情感韵律之声：近三十年的研究和未来方向

情绪化的声音引起了相当多的关注。在任何浏览器上使用“情感韵律”作为关键词进行搜索都会导致超过一百万个条目。这种兴趣在科学文献中也很明显。无数文章的介绍段落提醒读者韵律的重要性，听众很容易通过声音信息推断说话者的情绪状态。然而，尽管对该主题进行了数十年的研究并取得了重要成果，但声学和情绪状态之间的映射仍然不清楚。在本文中，我们为该领域的新手和寻求更新的研究人员绘制了有关情感韵律的丰富文献。我们还总结了过去几十年的文献样本所揭示的问题，并提出了解决这些问题的具体研究方向，最终满足对情感韵律更加机械化的知识的需求。
