	abstract = {<p>Humans, dolphins, and elephants are the only known species that vocally label their conspecifics. It remains unclear whether nonhuman primates share this ability. We recorded spontaneous ?phee-call? dialogues between pairs of marmoset monkeys. We discovered that marmosets use these calls to vocally label their conspecifics. Moreover, they respond more consistently and correctly to calls that are specifically directed at them. Analysis of calls from multiple monkeys revealed that family members use similar calls and acoustic features to label others and perform vocal learning. These findings shed light on the complexities of social vocalizations among nonhuman primates and suggest that marmoset vocalizations may provide a model for understanding aspects of human language, thereby offering new insights into the evolution of social communication. The ability to vocally label other individuals from your species and to learn these labels from others is a high-level cognitive function. Previously, this behavior has only been known to exist in humans, dolphins, and some parrot species. Oren et al. applied machine learning tools and real-time playback experiments to analyze naturally occurring ?phee-call? dialogues between pairs of marmoset monkeys. Marmosets used these vocalizations to label their conspecifics. They also perceived and responded correctly to calls that were specifically directed at them. Monkeys from the same family group used similar calls to vocally label others, and they learned from other family members to vocally label other individuals. ?Peter SternHumans, dolphins, and elephants are the only known species that vocally label their conspecifics.
