“…Reported symptoms of increased perceived vocal effort and measurable vocal fatigue include increased instability and breathiness, reduced agility and range, laryngeal discomfort, and increased phonation threshold pressures (PTP) [88][89][90]. The etiology of these symptoms is multifaceted and may arise (for example) from changes in vocal-fold viscosity, fatigue of intralaryngeal musculature and connective tissue, dehydration, or a combination of factors including these [91,92]. The nearly ubiquitous manifestation of vocal fatigue in functional, structural, and neurological dysphonia highlights its clinical significance [93].…”

To date, no established protocol exists for measuring functional voice changes in singers with subclinical singing-voice complaints. Hence, these may go undiagnosed until they progress into greater severity. This exploratory study sought to (1) determine which scale items in the self-perceptual Evaluation of Ability to Sing Easily (EASE) are associated with instrumental voice measures, and (2) construct as proof-of-concept an instrumental index related to singers’ perceptions of their vocal function and health status. Eighteen classical singers were acoustically recorded in a controlled environment singing an /a/ vowel using soft phonation. Aerodynamic data were collected during a softly sung /papapapapapapa/ task with the KayPENTAX Phonatory Aerodynamic System. Using multi and univariate linear regression techniques, CPPS, vibrato jitter, vibrato shimmer, and an efficiency ratio (SPL/PSub) were included in a significant model (p < 0.001) explaining 62.4% of variance in participants’ composite scores of three scale items related to vocal fatigue. The instrumental index showed a significant association (p = 0.001) with the EASE vocal fatigue subscale overall. Findings illustrate that an aeroacoustic instrumental index may be useful for monitoring functional changes in the singing voice as part of a multidimensional diagnostic approach to preventative and rehabilitative voice healthcare for professional singing-voice users.

“…Among the symptoms of hyperfunctional voice disorders, vocal fatigue is commonly the first to appear (Mahalingam et al, 2021;Nanjundeswaran et al, 2019). Given that hyperfunctional voice disorders are most common among occupational voice users, and that vocal fatigue symptoms may be tied to differences in voice production (e.g., Fujiki et al, 2021Fujiki et al, , 2022Kang et al, 2020;Milbrath & Solomon, 2003;Nanjundeswaran et al, 2017;Shembel & Nanjundeswaran, 2022), it would be informative to explore possible solutions to the auditorymotor phenotype that is influencing the development of voice disorders in this population.…”

Purpose: Altered auditory feedback research aims to identify methods to strengthen speakers' awareness of their own voicing behaviors, diminish their perception of vocal fatigue, and improve their voice production. This study aims to compare the effects of two bone conduction devices that provide altered auditory feedback. Method: Twenty participants (19–33 years old, age: M [ SD ] = 25.5 [3.85] years) participated in a vocal loading task using a standard Forbrain device that provides filtered auditory feedback via bone conduction and a modified Forbrain device that provides only sidetone amplification, and a control condition with no device was also included. They rated their vocal fatigue on a visual analog scale every 2 min during the vocal loading task. Additionally, pre- and postloading voice samples were analyzed for acoustic voice parameters. Results: Across all participants, the use of bone conduction–altered auditory feedback devices resulted in a lower vocal fatigue when compared to the condition with no feedback. During the pre- and postvoice samples, the sound pressure level decreased significantly during feedback conditions. During feedback conditions, spectral mean and standard deviation significantly decreased, and spectral skew significantly increased. Conclusion: The results promote bone conduction as a possible preventative tool that may reduce self-reported vocal fatigue and compensatory voice production for healthy individuals without voice disorders.
