Excessive vocal effort is a common clinical voice symptom, yet the acoustical manifestation of and how that perceived by speakers listeners has not been fully elucidated. Here, 26 vocally healthy adults increased during production utterance /ifi/, followed self-ratings on 100 mm visual analog scale. Twenty inexperienced assessed speakers' using sort-and-rate method. Previously proposed correlates were calculated, including: mean sound pressure level (SPL), fundamental frequency (fo),...

High-speed videoendoscopy was used to investigate how underlying laryngeal motor control strategies differ in individuals with and without hyperfunctional voice disorders (HVDs). Three kinematic measures were defined characterize control: stiffness, spatiotemporal index, asymmetry index. Twenty-eight adults HVDs 28 age- sex-matched controls produced repeated utterances of /ifi/ at three different gesture rates (50, 65, 80 beats per minute) self-induced vocal effort levels (mild, moderate,...

Purpose This study examined the relationship between acoustic measure relative fundamental frequency (RFF) and a kinematic estimate of laryngeal stiffness. Method Twelve healthy adults (mean age = 22.7 years, SD 4.4; 10 women, 2 men) produced repetitions /ifi/ while varying their vocal effort during simultaneous video nasendoscopic recordings. RFF was determined from last voicing cycles before voiceless obstruent (RFF offset) first revoicing onset). A stiffness ratio calculated for fold...

Purpose This study aimed to examine the relationship between a large set of hypothesized physiological measures vocal effort and self-ratings effort. Method Twenty-six healthy adults modulated speech rate during repetitions utterance /ifi/, followed by self-perceptual ratings on visual analog scale. Physiological included (a) intrinsic laryngeal tension via kinematic stiffness ratios determined from high-speed laryngoscopy, (b) extrinsic suprahyoid infrahyoid normalized percent activations...

Objectives/Hypothesis We investigated speech acoustics and self‐reported vocal symptoms in mask‐wearing healthcare professionals. hypothesized that there would be an attenuation of spectral energies increase effort during masked compared to unmasked speech. Study Design Within between subject quasi‐experimental design. Methods prospectively enrolled 21 providers (13 cisgender female, 8 male; M = 32.9 years; SD 7.9 years) assessed perceptual measures with without a face mask place....

Objective: Despite gender-affirming laryngological services (GALS; eg, voice therapy or surgery) being available nationwide, there is a discrepancy between the number of transgender and gender diverse (TGD) people with vocal incongruence those who pursue services. Primary care an important setting for accessing care, including learning about GALS. The purpose this study was to understand relationship access primary utilization Methods: An anonymous cross-sectional online survey developed in...

Purpose: The aim of this study was to explore the gap between need for gender-affirming voice and communication services (GAVCS) insurance coverage within one state. Method: An electronic, cross-sectional survey transgender/gender-diverse (TGD) adults assessed incidence cost barriers GAVCS. Then, policies from 22 major insurers were reviewed using a web-based search telephone inquiries. Finally, tool developed clinicians share available GAVCS by insurer. Results: Over half (53%) 115...

Purpose This study evaluated the accuracy of respiratory calibration methods for estimating lung volume during speech breathing. Method Respiratory kinematic data were acquired via inductance plethysmography in 32 young adults, 22 older and 13 adults with Parkinson's disease (PD). Raw rib cage (RC) abdomen (AB) signals (V) calibrated to liters using 4 correction methods: (a) isovolume maneuvers, (b) a constant 2:1 RC-to-AB ratio, (c) least squares method RC only (LsqRC), (d) both AB...

Purpose This study examined vocal hyperfunction (VH) using voice onset time (VOT). We hypothesized that speakers with VH would produce shorter VOTs, indicating increased laryngeal tension, and more variable disordered motor control. Method enrolled 32 adult women (aged 20–74 years) age- sex-matched controls. All were of American English. Participants produced vowel–consonant–vowel combinations varied by vowel (ɑ/u) plosive (p/b, t/d, k/g). VOT—measured at the release to initiation...

This study examined the relationship between magnitude of neck-surface vibration (NSVMag; transduced with an accelerometer) and intraoral estimates subglottal pressure (P'sg) during variations in vocal effort at 3 intensity levels.Twelve vocally healthy adults produced strings /pɑ/ syllables conditions, while increasing each condition. Measures were made P'sg (estimated stop-consonant closure), NSVMag (measured following vowel), sound level, respiratory kinematics. Mixed linear regression...

Objective Prephonatory vocal fold angle trajectories may supply useful information about the laryngeal system but were examined in previous studies using sigmoidal curves fit to data collected at 30 frames per second (fps). Here, high-speed videoendoscopy (HSV) was used investigate impacts of video frame rate and fitting strategy on adductory patterns for voicing onsets. Method Twenty-five participants with healthy voices performed /ifi/ sequences under flexible nasendoscopy 1,000 fps....

Relative fundamental frequency (RFF) is an acoustic measure that characterizes changes in voice during voicing transitions. Despite showing promise as indicator of vocal disorder and laryngeal muscle tension, the clinical adoption RFF remains challenging, partly due to a lack research integration. As such, this review sought provide summative information highlight next steps for implementation RFF. A systematic literature search was completed across 5 databases, yielding 37 articles met...

Smartphone technology has been used for at-home health monitoring, but there are few available applications (apps) tracking acoustic measures of voice those with chronic problems. Current apps limit the user by restricting range smartphone positions to that unnatural and non-interactive. Therefore, we aimed understand how more natural impacted accuracy in comparison clinically acquired derived measures. Fifty-six adults (11 vocally healthy, 45 disordered, aged 18-80 years) completed...

Purpose: The aim of this study was to characterize speech acoustics in bilingual preschoolers who speak Jamaican Creole (JC) and English. We compared a standard approach with culturally responsive for characterizing sound productions. Preschoolers' productions were adult models from the same linguistic community as means providing confirmatory evidence typical patterns specific JC–English speakers. Method: Two protocols applied data collected using Diagnostic Evaluation Articulation...

Purpose: This study examined the speech acoustic characteristics of Jamaican Creole (JC) and English in bilingual preschoolers adults using duration measures. The aims were to determine if, for JC English, (a) child adult differ, (b) differences occur preschoolers' patterns based on language spoken, (c) relationships exist between personal contextual factors (i.e., age, sex, percentage [%language] exposure use) duration. Method: Data this cross-sectional collected Kingston, Jamaica, New York...

Methods for automating relative fundamental frequency (RFF)-an acoustic estimate of laryngeal tension-rely on manual identification voiced/unvoiced boundaries from signals. This study determined the effect incorporating features derived vocal fold vibratory transitions boundary detection. Simultaneous microphone and flexible nasendoscope recordings were collected adults with typical voices (N=69) characterized by excessive tension (N=53) producing voiced-unvoiced-voiced utterances. Acoustic...

Purpose The goal of this study was to explore the relationships among vocal effort, extrinsic laryngeal muscle activity, and tract length (VTL) within healthy speakers. We hypothesized that increased effort would result in suprahyoid activation decreased VTL, as previously observed individuals with hyperfunction. Method Twenty-eight speakers American English produced vowel-consonant-vowel utterances under varying levels effort. VTL estimated from vowel formants. Three surface...
