Purpose Older patients with age-related voice changes (presbyphonia) are considered
vocal under-doers due to a reportedly low a amount and intensity of voice use (ie, low vocal …

Ambulatory voice monitoring is a promising tool for investigating phonotraumatic vocal
hyperfunction (PVH), associated with the development of vocal fold lesions. Since many …

Purpose Sound pressure level (SPL), fundamental frequency (F0), time dose (Dt), cycle
dose (Dc), and distance dose (Dd) are components affecting a vocal demand response. The …

Purpose The purpose of this study was to investigate the relationship between pitch
discrimination and fundamental frequency (fo) variation in running speech, with …

Objectives/Hypothesis In professional classical singing, an even voice quality throughout the
entire singing voice range is essential. Transitions between vocal registers (passaggio) are …

Glottal source characteristics vary between phonation types due to the tension of laryngeal
muscles with the respiratory effort. Previous studies in the classification of phonation type …

Background Neck surface accelerometer (NSA) wearable devices have been developed for
voice and upper airway health monitoring. As opposed to acoustic sounds, NSA senses …

Purpose: Although different factors and voice measures have been associated with
phonotraumatic vocal hyperfunction (PVH), it is unclear what percentage of individuals with …

Methods for automating relative fundamental frequency (RFF)—an acoustic estimate of
laryngeal tension—rely on manual identification of voiced/unvoiced boundaries from …

Objective: to verify the effects of the phonation exercise in a commercial straw on the voice of
teachers. Methods: a blind intervention study with a single group of teachers. The …
