Voiced speech is a highly complex process involving coupled interactions between the
vocal fold structure, aerodynamics, and acoustic field. Reduced-order lumped-element …

Motivation Human voice is generated in the larynx by the two oscillating vocal folds. Owing
to the limited space and accessibility of the larynx, endoscopic investigation of the actual …

Under certain conditions, eg, singing voice, the fundamental frequency of the vocal folds can
go up and interfere with the formant frequencies. Acoustic feedback from the vocal tract filter …

Human phonation is a highly non-linear process in which subglottal flow emanating from the
lungs induces self-oscillations of the vocal folds. In normal conditions, this results in the …

In an effort to mitigate the 2019 novel coronavirus disease pandemic, mask wearing and
social distancing have become standard practices. While effective in fighting the spread of …

As an alternative factor to produce asymmetry between left and right vocal folds, the present
study focuses on level difference, which is defined as the distance between the upper …

This study presents a framework for a direct comparison of experimental vocal fold dynamics
data to a numerical two-mass-model (2MM) by solving the corresponding inverse problem of …

The complex three-way interaction between airflow, tissue, and sound, for asymmetric vocal
fold vibration, is not well understood. Current modeling efforts are not able to explain clinical …

Voice production occurs through vocal cord and vibration coupled to glottal airflow. Vocal
cord lesions affect the vocal system and lead to voice disorders. In this paper, a pathological …

Previous vocal fold modeling studies have generally focused on generating detailed data
regarding a narrow subset of possible model configurations. These studies can be …
