As the primary means of communication, voice plays an important role in daily life. Voice
also conveys personal information such as social status, personal traits, and the emotional …

Phonation, or the vibration of the vocal folds, is the primary source of vocalization in the
production of voiced sounds by humans. It is a complex bio-mechanical process that is …

In the pathogenesis of COVID-19, impairment of respiratory functions is often one of the key
symptoms. Studies show that in these cases, voice production is also adversely affected …

Purpose: Vocal fold asymmetry creates irregular entrainments and modulations in voice,
which may lead to rough perceptual quality. The presence of asymmetry can also cause mid …

During phonation, the vocal folds exhibit a self-sustained oscillatory motion, which is
influenced by the physical properties of the speaker's vocal folds and driven by the balance …

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 …

Dysphonia is often caused by level difference between left and right vocal folds, which are
positioned on different angles with respect to the transverse plane, resulting in angular …

Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease that affects motor
neurons and causes speech and respiration dysfunctions. Current diagnostic methods are …

Simulation of the acoustics and biomechanics of sound production in humans and animals
began half a century ago. The three major components are the mechanics of tissue under …

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 …
