Reliability and Correlations Between Overall Severity, Roughness and Breathiness in the Perception of Dysphonic Voices: Investigating Cognitive Aspects.

Objectives: this study concerns the subjective perception of the quality of the voice, more particularly in the case of dysphonia. Our general objective is to study the perceptual mechanisms, which constitute Hirano's GRBAS multidimensional perceptual rating scale.

Material And Methods: We tested the reliability of the GRB perceptual scale both in terms of test-retest reliability (intra-listener stability) and in terms of inter-listener agreement.

Sunnybrook Facial Grading System: Intra-rater and Inter-rater Variabilities.

Objectives: Evaluate intra-rater and inter-rater variabilities of the Sunnybrook Facial Grading System (SFGS) and explore potential factors of variability.

Study Design: Prospective test of hypothesis.

Setting: University tertiary referral center.
