Objectives Vocal loading tasks provide insight regarding the mechanisms underlying
healthy laryngeal function. Determining the manner in which the larynx can most efficiently …

Purpose This study examined the relationship between the acoustic measure relative
fundamental frequency (RFF) and a kinematic estimate of laryngeal stiffness. Method Twelve …

Purpose The purpose of this article is to examine the ability of an acoustic measure, relative
fundamental frequency (RFF), to distinguish between two subtypes of vocal hyperfunction …

Relative fundamental frequency (RFF) is a promising acoustic measure for evaluating voice
disorders. Yet, the accuracy of the current RFF algorithm varies across a broad range of …

Objectives: Relative fundamental frequency (RFF) has shown promise as an acoustic
measure of voice, but the subjective and time-consuming nature of its manual estimation has …

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

Quantitative measures of laryngeal muscle tension are needed to improve assessment and
track clinical progress. Although relative fundamental frequency (RFF) shows promise as an …
