“…The findings in our study are parallel to the systematic review by Nair et al ., which reported a prevalence of between 33 and 68 per cent of voice disorders among call centre operators. 2 Similarly, a high prevalence rate of approximately 70 per cent was reported among telemarketers by several other studies. 7,8 The work burden of teleoperators working in a hospital may be reckoned to be lower compared with telemarketers.…”

Objective Teachers and singers have been extensively studied and are shown to have a greater tendency to voice disorders. This study aimed to investigate the correlation between subjective and objective voice analysis pre- and post-shift among teleoperators in a tertiary hospital. Methods This was a prospective cohort study. Each patient underwent pre- and post-shift voice analysis. Results Among 42 teleoperators, 28 patients (66.7 per cent) completed all the tests. Female predominance (62 per cent) was noted, with a mean age of 40 years. Voice changes during working were reported by 48.1 per cent. Pre- and post-shift maximum phonation time (p < 0.018) and Voice Handicap Index-10 (p < 0.011) showed significant results with no correlation noted between subjective and objective assessment. Conclusion Maximum phonation time and Voice Handicap Index-10 are good voice assessment tools. The quality of evidence is inadequate to recommend ‘gold standard’ voice assessment until a better-quality study has been completed.

“…The career prevalence of voice problems in call centre operators varies between 33 and 68 per cent. 2 Yet there is an urgent need for research to support occupational voice health and safety risk measurement, prevention and intervention. A meta-analysis published by Cutiva et al found a total of 18 cross-sectional studies.…”

“…Outside of the bone conduction studies, AAF research related to voice production has primarily been examined in daily life using self-reported symptoms as proxies for impaired voice production, especially in occupational voice users (Cutiva et al, 2013;Martins et al, 2014;Nair et al, 2021). However, alterations in voice production secondary to AAF can be more objectively quantified in laboratory settings through vocal loading tasks (VLTs), which aid in understanding how speakers without voice disorders respond vocally to challenging scenarios (Kelchner et al, 2006;Solomon & DiMattia, 2000;Stemple et al, 1995).…”

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.
