Morphological aspects of the euphonic voice

Folia Histochemica et Cytobiologica, 2011
The high quality of a euphonic voice is the result of complex interactions between many organs and systems. Vibrating vocal folds play a crucial role in this process.

A Contemporary Review of Clinical Factors Involved in Speech-Perspectives from a Prosthodontist Point of View

Medicina, 2023
Background and Objectives: Learning to speak properly requires a fully formed brain, good eyesight, and a functioning auditory system. Defective phonation is the outcome of a failure in the development of any of the systems or components involved in ...

Vortex Formation Times in the Glottal Jet, Measured in a Scaled-Up Model

Fluids, 2021
In this paper, the timing of vortex formation on the glottal jet is studied using previously published velocity measurements of flow through a scaled-up model of the human vocal folds.

Covariation Among Vowel Height Effects on Acoustic Measures [PDF]

, 2011
Covariation among vowel height effects on vowel intrinsic fundamental frequency (IF0), voice onset time (VOT), and voiceless interval duration (VID) is analyzed to assess the plausibility of a common physiological mechanism underlying variation in these ...

Implementation of an aeroacoustic simulation pipeline using openCFS-Acoustics and openCFS-Data applied to human phonation [PDF]

arXiv, 2023
The human phonation process be modeled using the Finite Element Method (FEM) which provides a detailed representation of the voice production process. A software implementation in C++ using FEM (openCFS) has been used to simulate the phonation process. The FEM model consists of a 3D mesh of the upper human airways.

Residual Attention Based Network for Automatic Classification of Phonation Modes [PDF]

arXiv, 2021
Phonation mode is an essential characteristic of singing style as well as an important expression of performance. It can be classified into four categories, called neutral, breathy, pressed and flow. Previous studies used voice quality features and feature engineering for classification.
