The purpose of the present study was to evaluate the usefulness of structuring perceptual voice characterizing categories by factor analysis and to provide data for a combined acoustic-perceptual evaluation of the vocal dysfunction. A set of normal and pathological voices representing various voice disorders were presented to a jury of voice clinicians who evaluated the voices on a five-point scale for each of 26 voice describing parameters. Factor analysis of the pathological subgroup of 26 voices revealed five bipolar factors accounting for 66% of the vocal variance. Significant correlations were found between three of these factors and acoustic data extracted from long-time average spectra, fundamental frequency distribution analysis and frequency perturbation. Also, some of the individual voice characterizing parameters correlated significantly with acoustic data.
