Evaluarea perceptual-acustică în patologia vocii cântate: scala GRBAS

Abstract

Traditional perceptual voice evaluation relies on the listener to make a subjective judgement on the type and severity of the dysphonic quality voice. GRBAS scale is typically used by clinicians to rate voice quality in patients who complain of dysphonia. The aim of this study is to verify the clinical applicability of GRBAS scale, to compare obtained scores before and after vocal therapy and to compare the findings with literature.
