A Study of Voice Handicap and Acoustic Measures in Arab Kuwaiti Prospective Professional Singers.

Despite its clinical significance, few studies have explored the applicability of the validated Arabic version of the Voice Handicap Index (VHI-Arab) in professional voice users, especially singers. The correlation between VHI-Arab scores and acoustic measures in this targeted group remains unclear. The aim of this study was to explore Arab Kuwaiti prospective professional singers' perception of voice handicap using the validated VHI-Arab. Additionally, we examined the association between VHI-Arab scores and acoustic measures such as fundamental frequency (F0), shimmer, jitter, and signal-to-noise ratio. VHI-Arab scores and acoustic measures of 100 adult prospective professional singers (50 females and 50 males) were compared with those of 100 adult controls (50 females and 50 males). Female prospective professional singers differed significantly from female controls in terms of functional and physical subscale scores, total VHI-Arab scores, and shimmer and jitter values. Male prospective professional singers showed significant differences neither in VHI-Arab scores nor in acoustic measures; however, their shimmer values showed significant a difference. There was no correlation between VHI-Arab scores and acoustic measures. Kuwaiti prospective professional singers did not perceive their voice as handicapped. Female prospective professional singers had a better perception of their voice compared with female controls. The results of the current study suggest that the perception of voice handicap and acoustic measures are different attributes that do not correlate.
