Abstract

The purpose of this thesis was to determine if male subjects would raise the fundamental frequency of their voice when given a vocal model by a female clinician. The 42 subjects were divided into four groups and each subject participated in two trials. This design, using these four groups, counter-balanced the data for gender and order effects. The Visi-Pitch Apple Interface (Kay Elemelrics Corporation, 1986) served as the fundamental frequency analyzer for all data. The mean fundamental frequencies produced by each group in Trial 1 and Trial 2 were subjected to an analysis of variance (ANOVA). Results indicated there was a significant group by trial interaction which suggested that the variables were interacting in a complex manner. However, results did indicate that a very high percentage (77%) of all the males in this study did raise the fundamental frequency of their voice when the stimulus provider was a female. This finding indicated the need for documentation or recognition of possible gender interaction when male subjects and female examiners/clinicians participate in data collection of pitch related vocal parameters.
