Purpose: The purpose of this study is to develop the Mandarin version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and evaluate its reliability compared with the Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS).
Method: The Mandarin version of the CAPE-V tool was translated from the validated English version with phonemic adaptations, content adjustment, and scale modification. Sixty dysphonic, 20 normal, and 20 repeated voice samples were included in this study. Ten of these were used for preassessment training; the remaining 90 were evaluated using the Mandarin CAPE-V and GRBAS for comparison of their interrater and intrarater reliabilities.
Results: Intrarater reliability was measured by Pearson r for the CAPE-V and Spearman rho for the GRBAS. Average CAPE-V Pearson r ranged from 0.80 for strain to 0.91 for overall severity, compared with average GRBAS Spearman rho of 0.83 for strain to 0.89 for asthenia. Interrater reliability was measured by an intraclass coefficient (ICC). Average CAPE-V ICCs ranged from .57 for pitch to .81 for overall severity, compared with average GRBAS ICCs of .60 for asthenia to .83 for grade.
Conclusions: The Mandarin CAPE-V addresses some limits of the English version. It also demonstrates good intrarater and interrater reliability, comparable to those of GRBAS.
