Purpose: The purpose of this study was to evaluate the reliability and validity of the Kannada version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). Method: The Kannada version of CAPE-V comprises six phrases that are phonetically designed as per the CAPE-V requirements. Sixty-five (21 individuals with dysphonia and 44 asymptomatic) participants were enrolled for the instrument psychometric validation. The interrater and intrarater reliability as well as validity were assessed. Results: High level of agreement was noted between the three raters across all the CAPE-V parameters, highest for pitch (intraclass correlation coefficient value = 0.98) and lowest for loudness (intraclass correlation coefficient value = 0.96). High intrarater reliability agreement (intraclass correlation coefficient value > 0.97) was also noted for all the parameters. Among the correlation for parameters that are comparable between CAPE-V and the Grade, Roughness, Breathiness, Asthenia, and Strain scale, the highest correlation was noted for overall severity. There was a significant difference noted between the study and control groups for all parameters except loudness. The discriminant function analysis and classification revealed that 98% were correctly identified. Conclusion: The Kannada version of CAPE-V has been proven to be a psychometrically reliable and valid tool to use for auditory-perceptual evaluation of voice.
