The field of animal vocal communication has benefited greatly from improved understanding
of vocal production mechanisms and specifically from the generalization of the source–filter …

The book aims to integrate our understanding of mammalian societies into a novel synthesis
that is relevant to behavioural ecologists, ecologists, and anthropologists. It adopts a …

On hearing a novel voice, listeners readily form personality impressions of that speaker.

It is well known that non-human animals respond to information encoded in vocal signals,
and the same can be said of humans. Specifically, human voice pitch affects how speakers …

Animals use acoustic signals for communication, implying that the properties of these
signals can be under strong selection. The acoustic adaptation hypothesis predicts that …

Vocalizations carry emotional, physiological and individual information. This suggests that
they may serve as potentially useful indicators for inferring animal welfare. At the same time …

Animals often use acoustical cues, such as formant frequencies, to assess the size of
potential mates and rivals. Reliable vocal cues to size may be under sexual selection. In …

The domestic cat is the only member of the Felidae to form social relationships with humans,
and also, the only small felid to form intraspecific social groups when free ranging. The latter …

Human voice pitch is sexually dimorphic and therefore conveys important information about
