Vocal production learning, the ability to modify the structure of vocalizations as a result of
hearing those of others, has been studied extensively in birds but less attention has been …

Humans and songbirds learn to sing or speak by listening to acoustic models, forming
auditory templates, and then learning to produce vocalizations that match the templates …

In nature, animal vocalizations can provide crucial information about identity, including
kinship and hierarchy. However, lab-based vocal behavior is typically studied during brief …

Research on the evolution of human speech and music benefits from hypotheses and data
generated in a number of disciplines. The purpose of this article is to illustrate the high …

The ability to vary the characteristics of one's voice is a critical feature of human
communication. Understanding whether and how animals change their calls will provide …

The field of bioacoustics is rapidly developing and characterized by diverse methodologies,
approaches and aims. For instance, bioacoustics encompasses studies on the perception of …

Animal vocalisations play a role in individual recognition and mate choice. In nesting
penguins, acoustic variation in vocalisations originates from distinctiveness in the …

Multimodal imitation of actions, gestures and vocal production is a hallmark of the evolution
of human communication, as both, vocal learning and visual-gestural imitation, were crucial …

Acoustic allometry is the study of how animal vocalizations reflect their body size. A key aim
of this research is to identify outliers to acoustic allometry principles and pinpoint the …

Despite extensive research on avian vocal learning, we still lack a general understanding of
how and when this ability evolved in birds. As the closest living relatives of the earliest …
