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 …

Individual recognition is critical in social animal communication, but it has not been
demonstrated for a complete vocal repertoire. Deciphering the nature of individual …

Recent advances in tagging and biologging technology have yielded unprecedented
insights into wild animal physiology. However, time-series data from such wild tracking …

Human speech possesses a rich hierarchical structure that allows for meaning to be altered
by words spaced far apart in time. Conversely, the sequential structure of nonhuman …

Many animals produce vocal sequences that appear complex. Most researchers assume
that these sequences are well characterized as Markov chains (ie that the probability of a …

Cattle mother-offspring contact calls encode individual-identity information; however, it is
unknown whether cattle are able to maintain individuality when vocalising to familiar …

Animal vocalizations play an important role in individual recognition, kin recognition, species
recognition, and sexual selection. Despite much work in these fields done on birds virtually …

Fundamental frequency (F 0, perceived as voice pitch) predicts sex and age, hormonal
status, mating success and a range of social traits, and thus functions as an important …

In humans, identity is partly encoded in a voice-print that is carried across multiple
vocalizations. Other species also signal vocal identity in calls, such as shown in the contact …

Automatic methods of classification of animal sounds offer many advantages including
speed and consistency in processing massive quantities of data. Calculations have been …
