鸟鸣的声学结构在频谱和时间上都很复杂。时间复杂度通常在关注符号歌曲序列统计特征的句法框架中进行研究。另外，时间模式可以在节奏框架中进行研究，重点关注歌曲元素之间的相对时间。在这里，我们通过对澳大利亚花斑伯劳鸟（Cracticus nigrogularis）歌曲的句法和节奏分析来研究这两种框架结合的优点，这些歌曲表现出有组织的句法和多样的节奏。我们表明，在我们的样本中，花斑屠夫鸟的歌曲回合的节奏是由歌曲的一阶顺序语法分类组织和预测的。即使在控制了音符长度的变化之后，这些歌曲的节奏仍然是分类分布的，并且与一阶顺序语法密切相关，这表明音符之间的无声间隔在音符序列上诱发了一种节奏结构。我们讨论了句法-节奏关系作为歌曲复杂性的相关特征的含义，并就人类语言和音乐等信号进行了讨论，并主张将歌曲复杂性的更广泛概念考虑到语法，节奏及其与其他声学和感知特征的相互作用。
The acoustic structure of birdsong is spectrally and temporally complex. Temporal complexity is often investigated in a syntactic framework focusing on the statistical features of symbolic song sequences. Alternatively, temporal patterns can be investigated in a rhythmic framework that focuses on the relative timing between song elements. Here, we investigate the merits of combining both frameworks by integrating syntactic and rhythmic analyses of Australian pied butcherbird (Cracticus nigrogularis) songs, which exhibit organized syntax and diverse rhythms. We show that rhythms of the pied butcherbird song bouts in our sample are categorically organized and predictable by the song’s first-order sequential syntax. These song rhythms remain categorically distributed and strongly associated with the first-order sequential syntax even after controlling for variance in note length, suggesting that the silent intervals between notes induce a rhythmic structure on note sequences. We discuss the implication of syntactic–rhythmic relations as a relevant feature of song complexity with respect to signals such as human speech and music, and advocate for a broader conception of song complexity that takes into account syntax, rhythm, and their interaction with other acoustic and perceptual features.
