“…While useful for exploring possible associations in a novel field, we acknowledge that the use of stepwise regression with backward elimination may have excluded some relevant parameters. This statistical approach is widely used in contemporary research (e.g., [124][125][126][127]), and here provides some proof-of-concept supporting further validation research, which should utilize a wider range of analyses including permutation statistics, applied to larger datasets. Some functional and perceptual changes in the singing voice may be traceable only intrasubject.…”

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.

“…This suggests a critical need to investigate the underlying properties of CI processing that lead to this and the design of processing strategies that can restore normal voice quality. Given the present voice acoustic results, it is likely that CI users also experience vocal fatigue 40 , and this highlights the critical need to pursue future research that examines self-reported voice-related quality of life in cochlear implant users 41 .…”

Cochlear implant users experience difficulties controlling their vocalizations compared to normal hearing peers. However, less is known about their voice quality. The primary aim of the present study was to determine if cochlear implant users’ voice quality would be categorized as dysphonic by the Acoustic Voice Quality Index (AVQI) and smoothed cepstral peak prominence (CPPS). A secondary aim was to determine if vocal quality is further impacted when using bilateral implants compared to using only one implant. The final aim was to determine how residual hearing impacts voice quality. Twenty-seven cochlear implant users participated in the present study and were recorded while sustaining a vowel and while reading a standardized passage. These recordings were analyzed to calculate the AVQI and CPPS. The results indicate that CI users’ voice quality was detrimentally affected by using their CI, raising to the level of a dysphonic voice. Specifically, when using their CI, mean AVQI scores were 4.0 and mean CPPS values were 11.4 dB, which indicates dysphonia. There were no significant differences in voice quality when comparing participants with bilateral implants to those with one implant. Finally, for participants with residual hearing, as hearing thresholds worsened, the likelihood of a dysphonic voice decreased.

Objectives: This study aimed to investigate the vocal changes in adults experiencing subjective vocal fatigue through a three-week intervention employing a semi-occluded ventilation mask (SOVM), which is a type of semi-occluded vocal tract exercise (SOVTE), and Korean speech materials. Methods: We implemented a three-week intervention program using an SOVM and a protocol based on Korean speech materials for 22 Korean adults (5 males and 17 females, aged 25.81 ± 7.31 years) reporting subjective vocal fatigue. The SOVM was fabricated by establishing a semi-occluded environment using a silicone plug with a central hole, which was inserted into the front opening of an air-cushion mask, typically used in medical context. Participants were also instructed to perform home training sessions twice a day until the subsequent intervention. The outcomes of multi-dimensional voice evaluations were compared pre- and post-intervention to assess vocal changes. Results: Post-intervention, significant improvements were observed in specific acoustic measurements (jitter percent, shimmer percent, noise-to-harmonic ratio, and cepstral peak prominence of vowel phonation) and the severity indices derived from those acoustic parameters. Additionally, a significant reduction in patient-reported outcome measures was noted following the intervention. Conclusion: The findings suggest that voice intervention using the SOVM and Korean speech materials has the potential to alleviate vocal fatigue and enhance vocal quality in individuals with vocal fatigue complaints.
