Abstract
OBJECTIVES/HYPOTHESIS: The purpose of this study was to determine the effect of experience on the perceptual space of listeners when judging voice quality. STUDY DESIGN: This was a within-subjects group design. METHOD: Speech-language pathologists, singing voice teachers, speech-language pathology graduate students with and without experience with a voice client, graduate students who have completed a voice pedagogy course, and inexperienced served as listeners. Each participant rated the similarity of pairs of synthesized stimuli with systematically altered measurements of jitter, shimmer, and noise-to-harmonics ratio on a visual analog scale ranging from no similarity to extremely similar. RESULTS: Results showed that participants with different levels and types of experience used different perceptual spaces (of additive noise and perturbation measures) when judging the similarity of stimulus pairs. CONCLUSION: The conclusion was that perceptual spaces differ among individuals with different levels and types of experience when judging the similarity of pairs of stimuli with systematically altered acoustical measurements.
