Editor’s summaryThe 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.
