Sound and movement are entangled in animal communication. This is obviously true in the case of sound-constituting vibratory movements of biological structures which generate acoustic waves. A little less obvious is that other moving structures produce the energy required to sustain these vibrations. In many species, the respiratory system moves to generate the expiratory flow which powers the sound-constituting movements (sound-powering movements). The sound may acquire additional structure via upper tract movements, such as articulatory movements or head raising (sound-filtering movements). Some movements are not necessary for sound production, but when produced, impinge on the sound-producing process due to weak biomechanical coupling with body parts (e.g., respiratory system) that are necessary for sound production (sound-impinging movements). Animals also produce sounds contingent with movement, requiring neuro-physiological control regimes allowing to flexibly couple movements to a produced sound, or coupling movements to a perceived external sound (sound-contingent movement). Here, we compare and classify the variety of ways sound and movements are coupled in animal communication; our proposed framework should help structure previous and future studies on this topic.
声音和运动在动物交流中是交织在一起的。这在由生物结构的振动运动构成的产生声波的声音中显然是正确的。不太明显的是，其他运动结构产生维持这些振动所需的能量。在许多物种中，呼吸系统移动以产生为声音构成运动（发声运动）提供动力的呼气流。声音可能通过上呼吸道运动（例如，发音运动或抬头）获得额外的结构（滤波运动）。有些运动不是发声所必需的，但当产生时，由于与发声（发声运动）所需的身体部位（例如呼吸系统）的弱生物力学耦合，会对发声过程产生影响。动物也会产生与运动相关的声音，需要神经生理控制机制来灵活地将运动与产生的声音耦合，或将运动与感知到的外部声音耦合（声音相关的运动）。在这里，我们比较和分类了动物交流中声音和运动耦合的各种方式；我们提出的框架应该有助于构建以前和未来关于这个主题的研究。
