我们研究哪些声学特征是相关的棉顶绢毛猴（Saguinus俄狄浦斯）组合长呼叫识别。这种由雄性和雌性发出的声音，在维持群体凝聚力，领土防御和配偶吸引力方面发挥作用。使用绢毛猴的自然对唱的声音反应，听到一个组合长的呼叫作为识别的主要措施，我们提出了主题与合成的组合长的呼叫，我们操纵在三个声学维度之一：频率，时间和振幅的样本。结果表明，虽然在频域和时域的声学特征是重要的组合长呼叫识别，在音节内和之间的幅度的变化不是。此外，虽然基本频率似乎被用于编码关于频率轮廓的信息，但是时间信息是从谐波导出的。总的来说，这些结果表明，绢毛猴使用一套特定的声学特征组合长呼叫识别。
We examine which acoustic features are relevant for recognition of the cotton-top tamarin (Saguinus oedipus) combination long-call. This vocalization, emitted by both males and females, functions in maintaining group cohesion, territory defense and mate attraction. Using the tamarins' natural antiphonal vocal response to hearing a combination long-call as the primary measure of recognition, we presented subjects with synthetic exemplars of combination long-calls in which we manipulated across one of three acoustic dimensions: frequency, time and amplitude. Results indicated that although acoustic features in the frequency and time domains are important for combination long-call recognition, the changes in amplitude within and between syllables are not. Furthermore, while the fundamental frequency appears to be the used to encode information about the frequency contour, the temporal information is derived from the harmonics. Overall, these results suggest that tamarins use a specific suite of acoustic features for combination long-call recognition.
