A Framework for Bioacoustic Vocalization Analysis Using Hidden Markov Models [PDF]

Algorithms, 2009
Using Hidden Markov Models (HMMs) as a recognition framework for automatic classification of animal vocalizations has a number of benefits, including the ability to handle duration variability through nonlinear time alignment, the ability to incorporate ...

Animal Species Classification from Vocalizations Using Cochlear-Inspired Audio Features and Machine Learning [PDF]

Biomimetics
Biomimetic approaches have gained increasing attention in the development of efficient computational models for sound scene analysis. In this paper, we present a sound-based animal species classification method inspired by the auditory processing ...

What is vocology?

Revista de Investigación e Innovación en Ciencias de la Salud, 2021
In its broadest definition, Vocology is the study of vocalization, much like audiology is the study of hearing. Vocology includes the exploration of the full capability of human and animal sound production, some of which is embedded in human speech.

Acoustic sensors for detecting cow behaviour

Smart Agricultural Technology, 2023
Acoustic technologies provide a non-invasive method to generate information about the health, welfare, and environmental impact of livestock. This study demonstrated that rear leg attached acoustic sensors can be used to differentiate between seven ...

Increased self-triggered vocalizations in an epidermal growth factor-induced rat model for schizophrenia

Scientific Reports, 2022
Rats elicit two types of ultrasonic vocalizations (USVs), positive (30–80 kHz; high pitch) and negative (10–30 kHz; low pitch) voices. As patients with schizophrenia often exhibit soliloquy-like symptoms, we explored whether an animal model for ...

Origins of scale invariance in vocalization sequences and speech. [PDF]

PLoS Computational Biology, 2018
To communicate effectively animals need to detect temporal vocalization cues that vary over several orders of magnitude in their amplitude and frequency content.

A Protocol for the Non-invasive Method of Ultrasound Separation During the Sociosexual Vocal-Non-contact Model in Rats

Frontiers in Behavioral Neuroscience, 2022
Ultrasonic vocalization (USV) is one of the measurable behavioral parameters of sociosexual interactions in rats. To precisely and accurately describe the neurobehavioral properties of USV and the potentially related specific emotional responsiveness of ...

A possible common physical principle that underlies animal vocalization: theoretical considerations with an unsteady airflow-structure interaction model

Journal of Biomechanical Science and Engineering, 2016
We previously described an analytical model regarding how human falsetto voice is produced upon interaction between the respiratory airflow and vocal fold motion.
