Abstract

Vocal symptoms of patients with chronic and incipient spastic dysphonia were compared on a number of acoustic and perceptual parameters. Patients with incipient spastic dysphonia displayed less severe strain-strangle pronation, effort, rhythm, and stress. Harshness was die only perceptual parameter on which incipient spastic dysphonics were rated higher than chronic spastic dysphonics. Changes in the acoustic measures of laryngealiza-tion, harmonic change, mean vowel duration, and duration ratio between stressed and unstressed vowels accompanied changes in listeners' perception of strain-strangle' phonation and effort. The variation in acoustic characteristics such as laryngealization and harmonic change as well as normal phonation indicated that both groups were characterized by a variety of phonatory modes.
