A total of 473 samples of normal and pathological voices were classified by a group of experienced listeners according to three factors of the Isshiki scale (degree of hoarseness, roughness, breathiness, four point grading). The same material was processed by long-term average spectral analysis (L T AS). The results were related to each other using multivariate variance and discriminant analyses and error estimating procedures regarding the share of correct reclassifications (based on the spectral data) into the subjective classes. Probability of correct reclassification reached a level of c. 50%. Cluster analyses (four clusters) of the spectral data with no primary reference to the auditive classification demonstrated that each of the clusters covered samples from several auditive classes. Auditory reevaluation by a second series of listening tests show results of a very high level of concordance compared to the first tests. Reclassification programs regarding the clusters reached a probability of correctness ranging from 77 to 85%. Thus, LTAS data can be separately structuralized and may help to confirm classifications of individual clinicians. For the time being, groups of listeners reveal the most reliable classification of voice qualities.
