Abstract

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.
