Major Depressive Disorder Discrimination Using Vocal Acoustic Features

Journal of Affective Disorders, 2018
BACKGROUND The voice carries various information produced by vibrations of the vocal cords and the vocal tract. Though many studies have reported a relationship between vocal acoustic features and depression, including mel-frequency cepstrum coefficients

Deep learning in automatic detection of dysphonia: Comparing acoustic features and developing a generalizable framework.

International journal of language and communication disorders, 2022
BACKGROUND Auditory-perceptual assessment of voice is a subjective procedure. Artificial intelligence with deep learning (DL) may improve the consistency and accessibility of this task. It is unclear how a DL model performs on different acoustic features.

The acoustic features of human laughter

The Journal of the Acoustical Society of America, 2001
Remarkably little is known about the acoustic features of laughter. Here, acoustic outcomes are reported for 1024 naturally produced laugh bouts recorded from 97 young adults as they watched funny video clips. Analyses focused on temporal features, production modes, source- and filter-related effects, and indexical cues to laugher sex and individual ...

Acoustic Emission Recognition Based on Spectrogram and Acoustic Features

2020
In order to improve the level and efficiency of fault diagnosis, an acoustic emission recognition method based on spectrum and acoustic features is proposed. The proposed system is composed of CNN and BiLSTM networks. Firstly, the amplitude spectrum and group delay phase spectrum of AE signals are extracted, and the amplitude-phase spectrum composed of
