We present a model of sound production in a songbird's vocal organ and find that much of the complexity of the song of the canary (Serinus canaria) can be produced from simple time variations in forcing functions. The starts, stops, and pauses between syllables, as well as variation in pitch and timbre are inherent in the mechanics and can often be expressed through smooth and simple variations in the frequency and relative phase of two driving parameters
我们提出了一种鸣禽发声器官的发声模型，并发现金丝雀（Serinus canaria）歌声的许多复杂性可以由强迫函数的简单时间变化产生。音节之间的起始、停止和停顿，以及音高和音色的变化都存在于其发声机制中，并且通常可以通过两个驱动参数的频率和相对相位的平滑简单变化来表达。
