Animals, 2019 Over the last few years, an increasing number of studies have aimed to gain more insight into the field of animal emotions. In particular, it is of interest to determine whether animals can cross-modally categorize the emotions of others.

Ultrasonic vocalization of pup and adult fat-tailed gerbils (Pachyuromys duprasi)
PLoS ONE, 2019 Ultrasonic vocalizations (USVs) of laboratory rodents indicate animal emotional arousal and may serve as models of human disorders. We analysed spectrographically USV calls of pup and adult fat-tailed gerbils Pachyuromys duprasi during 420-s tests ...

Distributed acoustic cues for caller identity in macaque vocalization [PDF]
Royal Society Open Science, 2015 Individual primates can be identified by the sound of their voice. Macaques have demonstrated an ability to discern conspecific identity from a harmonically structured ‘coo’ call.

Scientific Reports, 2017 Throughout life, rats emit ultrasonic vocalizations (USV) when confronted with an aversive situation. However, the conditions classically used to elicit USV vary greatly with the animal’s age (isolation from the dam in infancy, versus nociceptive ...

Evidence of auditory insensitivity to vocalization frequencies in two frogs
Scientific Reports, 2017 The emergence and maintenance of animal communication systems requires the co-evolution of signal and receiver. Frogs and toads rely heavily on acoustic communication for coordinating reproduction and typically have ears tuned to the dominant frequency ...

Animation Synthesis Triggered by Vocal Mimics [PDF]
Motion, Interaction and Games, 2019 We propose a method leveraging the naturally time-related expressivity of our voice to control an animation composed of a set of short events. The user records itself mimicking onomatopoeia sounds such as "Tick", "Pop", or "Chhh" which are associated with specific animation events.

Combinatoriality in the vocal systems of nonhuman animals [PDF]
WIREs Cognitive Science, 2019 A key challenge in the field of human language evolution is the identification of the selective conditions that gave rise to language's generative nature. Comparative data on nonhuman animals provides a powerful tool to investigate similarities and differences among nonhuman and human communication systems and to reveal convergent evolutionary ...

The syntax–semantics interface in animal vocal communication [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2019 Syntax (rules for combining words or elements) and semantics (meaning of expressions) are two pivotal features of human language, and interaction between them allows us to generate a limitless number of meaningful expressions. While both features were traditionally thought to be unique to human language, research over the past four decades has revealed

Vocal repertoire and individuality in the plains zebra (Equus quagga)
Royal Society Open ScienceAcoustic signals are vital in animal communication, and quantifying them is fundamental for understanding animal behaviour and ecology. Vocalizations can be classified into acoustically and functionally or contextually distinct categories, but ...

Optimal features for auditory categorization
Nature Communications, 2019 Vocalizations such as speech or animal calls have high variability in production. Here, the authors report that a few mid-level acoustic features provide sufficient information to generalize across this variability and classify vocalization types and ...
