OBJECTIVES: Vocal fold vibration onset delay (VFVOD) is heard frequently in spasmodic dysphonia and in muscle tension dysphonia. VFVOD changes due to other vocal pathologies have not been investigated. VFVOD during sustained vowel production was estimated with high-speed video in 10 normal and 40 pathologic subjects (scars, vocal fold paralysis, vocal fold nodules, and polyps). Analysis of high-speed video was done using digital kymography. RESULTS: VFVOD can be divided into two portions...

Purpose: Vocal hyperfunction, related to abnormal laryngeal muscle activity, is considered the proximal cause of primary muscle tension dysphonia (pMTD). Relative fundamental frequency (RFF) has been proposed as an objective acoustic marker of vocal hyperfunction. This study examined (a) the ability of RFF to track changes in vocal hyperfunction after treatment for pMTD and (b) the influence of dysphonia severity, among other factors, on the feasibility of RFF computation. Method: RFF calculations and dysphonia severity ratings were derived from pre- and posttreatment recordings from 111 women with pMTD and 20 healthy controls...

OBJECTIVES: The purpose was to assess whether cervical muscular contraction during phonation influences the period and amplitude perturbation quotients (PPQ and APQ, respectively) of electroglottographic (EGG) signals, and whether high-pass filtering can attenuate these effects. STUDY DESIGN: Prospective. METHODS: We included 19 nondysphonic speakers and 21 patients with muscle tension dysphonia. During the recording of acoustic and EGG signals, each participant was instructed to naturally phonate sustained vowels /i:/ and /a:/ (NP tasks), and additionally, each nondysphonic participant was asked to phonate the same vowels in a nondysphonic voice quality while contracting the cervical muscles (muscular contracted phonation [MCP] tasks)...

REVIEW
C Kiese-Himmel
The etiopathogenesis of functional dysphonia is complex; it is not sufficient to look solely at vocal behavior aspects. The predisposing basis for functional dysphonia can lie in the constitution of an individual, his/her professional speaking and speech behavior and/or may be personality-based. (Prolonged) psychosocial stress, vocal overstressing, unfavorable speaking habits, infection of the upper respiratory tract, inflammatory processes in the larynx, emotional life events and COSO events are considered as possible triggers...
