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 = .98) and lowest for loudness (intraclass correlation coefficient value = .96). High intrarater reliability agreement (intraclass correlation coefficient value > .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.
