Perceptual and acoustic correlates of abnormal voice qualities.
A set of 17 voices representing various voice disorders were presented to a jury of voice experts who rated them on a 5-point scale for each of 28 terms frequently used for describing voices. A statistical treatment of these ratings yielded 5 bipolar factors accounting for 85% of the total variance. Significant correlations were found between four of these factors and certain acoustic data extracted fron long-time-average spectra and fundamental frequency distribution analysis of the same voice sample.
