通过声音识别个体常常被认为是社会物种中的一种重要现象。目前对侏儒狨猴（Cebuella pygmaea）的研究表明，在两种接触叫声中，每一种都有独特的声学特征，通过这些特征可以将个体区分开来。个体侏儒狨猴的反应不同，这取决于发出接触呼叫的类型和发声动物的身份。通过隐藏的扬声器回放的个人呼叫产生了一些不同的个人反应的证据，但只有当它们来自熟悉的位置时。这些结果表明，侏儒狨猴通过他们的接触呼叫来识别彼此。
Individual recognition by voice has been frequently assumed to be an important phenomenon in the social species. The present study on pygmy marmosets (Cebuella pygmaea) demonstrated that there are distinctive acoustic features in each of two contact calls by which individuals could be distinguished from each other. Individual pygmy marmosets responded differently depending on which type of contact call was given and on the identity of the vocalizing animal. Playbacks of individual calls through hidden speakers produced some evidence for differential individual responses, but only when they originated from familiar locations. These results indicate that pygmy marmosets recognize each other on the basis of their contact calls.
