Purpose: Despite the high prevalence of primary muscle tension dysphonia (MTD-1), its
underlying mechanisms and their interrelationships have yet to be fully identified. The …

Purpose The purpose of this viewpoint article is to facilitate research on vocal hyperfunction
(VH). VH is implicated in the most commonly occurring types of voice disorders, but there …

Relative fundamental frequency (RFF) is an acoustic measure that characterizes changes in
voice fundamental frequency during voicing transitions. Despite showing promise as an …

Excessive vocal effort is a common clinical voice symptom, yet the acoustical manifestation
of vocal effort and how that is perceived by speakers and listeners has not been fully …

Purpose: The purpose of this study was to measure the short-term effects of circumlaryngeal
massage and laryngeal reposturing on acoustic and perceptual characteristics of voice in …

Objectives/Hypothesis We investigated speech acoustics and self‐reported vocal symptoms
in mask‐wearing healthcare professionals. We hypothesized that there would be an …

Purpose This study examined vocal hyperfunction (VH) using voice onset time (VOT). We
hypothesized that speakers with VH would produce shorter VOTs, indicating increased …

Purpose The purpose of this study was to determine the effect of cognitive load on relative
fundamental frequency (RFF) in individuals with healthy voices. Method Twenty adults with …

Purpose: Autonomic nervous system dysfunction has been implicated in the development
and persistence of hyperfunctional voice disorders (HVDs). The purpose of this study was to …

The acoustic measure, relative fundamental frequency (RFF), has been proposed as an
objective metric for assessing vocal hyperfunction; however, its underlying physiological …
