Audio-Perceptual Evaluation of Portuguese Voice Disorders—An Inter- and Intrajudge Reliability Study

Objectives/Hypothesis The aim of this article was to describe the results of an audio-perceptual evaluation carried out by 10 judges, on a database comprising 90 voice recordings plus 10 samples repetition, with the purpose of characterizing the intra- and interrater reliability. Study Design Exploratory, transversal. Methods The classification of the GRBAS parameters was obtained for each one of the 10 experts, concerning the 90 voice samples. The intraclass correlation coefficient determined the interrater reliability. For the 10 repeated voices, the intrarater reliability was assessed by means of a dispersion analysis. Results The average judgesʹ classification for each of the GRBAS parameters differs (Pآ آ 0.05).
