Thus, each individual is daily exposed to a large number of CVs from several callers ( Snowdon 1986 Hauser 1996). Most non-human primates possess a rich vocal repertoire, which they use in many different contexts, such as agonistic or affiliative interactions with members of their social group, territorial calls and alarm calls, many of them loud enough to be heard at a distance (e.g. In the auditory environment of primates, vocalizations produced by a conspecific individual-conspecific vocalizations (CVs)-are sounds of overriding importance.

are they analysed using dedicated cerebral mechanisms not used for other sound categories, and (ii) to what extent and using what neural mechanisms do primates identify conspecific individuals from their vocalizations? In this comparative review, we focus on behavioural and neurobiological evidence relative to two issues central to voice perception in human and non-human primates: (i) are CVs ‘special’, i.e.

Studying the neural bases of voice perception in primates thus not only has the potential to shed light on cerebral mechanisms that may be-unlike those involved in speech perception-directly homologous between species, but also has direct implications for our understanding of how speech appeared in humans. Speech perception is likely to have evolved in our ancestors on the basis of pre-existing neural mechanisms involved in extracting behaviourally relevant information from conspecific vocalizations (CVs). Part of the animal sound library, a set of wildlife sound effects providing cries and calls of wild animals: sounds of reptiles, roar of big cats, monkey, wolf and elephants, sound effects of animals from savanna and forest.Humans share with non-human primates a number of voice perception abilities of crucial importance in social interactions, such as the ability to identify a conspecific individual from its vocalizations.
