title: Acoustic and perceptual indicators of normal and pathological voice.
abstract: The aim of this study was to obtain acoustic correlates to vocal quality of a group of men and women with and without voice disorders, based on evaluations of a group of judges experienced in the field of vocal rehabilitation. In male subjects, perceptual evaluation of normal, hoarse and rough voice qualities was related to the following acoustic features: frequency perturbation measures (JITA, RAP, and SPPQ), amplitude perturbation (SAPQ and VAM), soft phonation index (SPI) and fundamental frequency tremor intensity (FTRI). While these measures presented normal values for normal voice, hoarseness showed some deviations in perturbation frequency variables and very high SPI values, while rough voice showed deviations in all the measures. Qualities of female voices were perceived as normal, breathy and hoarse, but the acoustic correlates of these qualities were less conclusive.
