Abstrakt: Listeners matched the pitch of 36 clear to severely dysphonic vowels to the frequency of pure tones produced by a signal generator. Mean difference scores on pitch match correlated-.56 with jitter, -51 with jitter ratio, -.57 with spectrographic noise classifications, and -.64 with vocal roughness. Moderately to severely dysphonic vowels received significantly lower pitch match values than clear to mildly dysphonic vowels. Findings suggest that the effect of vocal roughness on pitch should be considered by the clinician who makes use of perceptual judgments.
