We review behavioural and neural evidence for the processing of information contained in conspecific vocalizations (CVs) in three primate species: humans, macaques and marmosets. We focus on abilities that are present and ecologically relevant in all three species: the detection and sensitivity to CVs; and the processing of identity cues in CVs. Current evidence, although fragmentary, supports the notion of a "voice patch system" in the primate brain analogous to the face patch system of visual cortex: a series of discrete, interconnected cortical areas supporting increasingly abstract representations of the vocal input. A central question concerns the degree to which the voice patch system is conserved in evolution. We outline challenges that arise and suggesting potential avenues for comparing the organization of the voice patch system across primate brains.
我们回顾了人类、猕猴和狨猴这三种灵长类动物处理同种发声（CVs）中所含信息的行为和神经学证据。我们关注的是这三种物种都具备且与生态相关的能力：对CVs的检测和敏感度；以及对CVs中身份线索的处理。目前的证据虽然零碎，但支持灵长类大脑中存在类似于视觉皮层面部区域系统的“声音区域系统”这一观点：一系列离散且相互连接的皮层区域，支持对声音输入越来越抽象的表征。一个核心问题是声音区域系统在进化过程中的保守程度。我们概述了出现的挑战，并提出了比较不同灵长类大脑中声音区域系统组织的潜在途径。
