Distinct Cortical Pathways for Processing Tool versus Animal Sounds

Journal of Neuroscience, 2005
Human listeners can effortlessly categorize a wide range of environmental sounds. Whereas categorizing visual object classes (e.g., faces, tools, houses, etc.) preferentially activates different regions of visually sensitive cortex, it is not known ...

TinyML-Based Swine Vocalization Pattern Recognition for Enhancing Animal Welfare in Embedded Systems

Inventions
The automatic recognition of animal vocalizations is a valuable tool for monitoring pigs’ behavior, health, and welfare. This study investigates the feasibility of implementing a convolutional neural network (CNN) model for classifying pig vocalizations ...

Spontaneous rhythms in a harbor seal pup calls

BMC Research Notes, 2018
Objectives Timing and rhythm (i.e. temporal structure) are crucial, though historically neglected, dimensions of animal communication. When investigating these in non-human animals, it is often difficult to balance experimental control and ecological ...

Animal Vocalization Analysis and Synthesis

, 2014
This Master’s thesis focuses on the unexplored domain of animal vocalizations. In the present work Lemur (madagascarian mammal) vocalizations are studied and analysed in order to create a system that can process and train datasets and posteriorly synthesize vocalizations. To achieve the goal the technique of Hidden Markov Models based synthesis is used

Speech-induced suppression and vocal feedback sensitivity in human cortex

eLife
Across the animal kingdom, neural responses in the auditory cortex are suppressed during vocalization, and humans are no exception. A common hypothesis is that suppression increases sensitivity to auditory feedback, enabling the detection of vocalization

Vocal changes in animals during disorders

, 2000
Welchen Einfluß hat eine Erkrankung der lautgenerierenden Strukturen auf das Lautprodukt. Wie kann eine Stimmveränderung beschrieben werden? Diese Fragen waren zentrales Thema der Untersuchungen. Es wurde ausschließlich auf Senderseite gearbeitet und das akustische Signal und sein Generierungsmechanismus betrachtet.

Vocal membranes lower the phonation threshold pressure in rhesus macaques (Macaca mulatta)

Royal Society Open Science
The vocal membrane, an extended part of the vocal fold, is present in a broad range of species including non-human primates. Its contribution to animal vocalizations has long been of interest. A theoretical study (Mergell P, Fitch T, Herzel H.

Comparative histology of the vocal sac in three species of hylid frogs with comments on its functional correlates

Phyllomedusa: Journal of Herpetology, 2023
The vocal sacs of frogs are elastic structures responsible for the circulation of air during vocalization, amplifying the sounds produced by these animals during multimodal communication.
