Comparative contrast of voice measurements

Currently, a variety of objective and subjective measures are available to describe voice and voice function. Despite these various tools, there is no standard measure of voice function that incorporates both objective and su bjective measures. The goal of this research was to study the relationship between objective, subjective, and patient-based measures of voice function , Objective voice function was measured with 4 laboratory-based parameters (subglottic pressure, airflow at the lips, maximum phonation time, and voca l efficiency), subjective function with the GRBAS (grade, rough, breathy, a sthenic, strained) scale, and patient-based function according to an overal l global rating of quality. The objective and subjective measures were sign ificantly related to each other (P < 0.05); the objective and patient-based measures were also related (P = 0.019), but the subjective and patient-bas ed measures were not related. We demonstrate a significant relationship bet ween some but not all measures of voice function. We believe that subjectiv e measures provide additional valuable information not obtained from object ive measures alone.
