Auditory-perceptual analysis of voice signals from patients with vocal fold scar and sulcus vocalis and controls (n = 23 in each group). Each signal token was rated five times each by three raters (i.e., 15 total ratings per token) using a seven point equal-appearing-interval scale representing overall voice quality (1: normal; 7: largest deviation from normal). Multiple ratings were then averaged within each rater followed by across raters. A: Comparison of mean perceptual rating of voice quality for patients and controls. B: Bland-Altman analysis of auditory-perceptual rating reliability across raters. Grey solid lines represent perfect agreement; black dashed lines represent mean bias; red dashed lines represent upper and lower limits of agreement (set at 95%).
