Perceptual Correlates Of Acoustic Measures Of Vocal Variability, Bree Ann Cumbers

Theses and Dissertations

This study investigated relationships between acoustic measures of vocal variability (pitch sigma, SFF range) and perceptual ratings of vocal variability during a reading task. Fifteen male (19-30 years of age) and nineteen female speakers (20-30 years of age) who were recorded reading the Grandfather Passage provided the stimuli for the listening task. From these samples, 30 were selected as representing a continuum of degrees of vocal variability. Male (N = 15) and female (N = 15) samples were presented to listeners separately. Thirty graduate students in Communication Sciences and Disorders who had a course background in voice supplied the perceptual …
