在这项工作中，我们对鸟鸣产生过程中唇部振荡的简单二维模型所显示的动力学进行了分析。我们证明，能够生成音调声音的同一模型可以针对各种参数提供频谱丰富的解决方案。在每个振荡状态中讨论了生理上敏感参数的作用，使我们能够解释以前报告的数据。
In this work we present an analysis of the dynamics displayed by a simple bidimensional model of labial oscillations during birdsong production. We show that the same model capable of generating tonal sounds can present, for a wide range of parameters, solutions which are spectrally rich. The role of physiologically sensible parameters is discussed in each oscillatory regime, allowing us to interpret previously reported data.
