Abstract

Objective: The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was developed to assess voice quality. The aim of this study was to develop a Turkish adaptation of CAPE-V and to evaluate the reliability and validity of the Turkish version. Methods: To adapt the CAPE-V protocol to Turkish, six sentences were constructed to meet the phonetic requirements. The validity of the Turkish version of the CAPE-V was tested with inter-rater reliability, intrarater reliability, and GRBAS versus the CAPE-V judgments. Ninety-nine dysphonic and 83 healthy subjects were enrolled. Results: High inter-rater and intrarater reliability (ICC > 0.88, r > 0.81, respectively) were obtained for all vocal parameters. The differences in the six CAPE-V parameters between healthy and dysphonic subjects were statistically significant (P < 0.0001). The correlations between CAPE-V and GRBAS scales were high in overall severity-grade and roughness parameters (r = 0.85, r = 0.82, respectively), the lowest correlation was the strain parameter (r = 0.66). Conclusion: The Turkish version of CAPE-V is a reliable and valid instrument for auditory-perceptual evaluation of the Turkish speaking population.
