PERCEPTIONS OF VOICE PRODUCTION IN HEALTHY FEMALES IN REGARDS TO AGE AND PROFESSIONALISM : AS QUANTIFIED BY ACOUSTIC AND PERCEPTUAL MEASURES

Summary

PURPOSE: This study aims to research the perception of voice as it relates to aging and professionalism in an individual. The production of voice varies in accordance with various factors. These variations often provide an insight into a listener’s perceptions of a speaker’s vocal characteristics and these perceptions may vary across settings. METHODS: This study required four components. The first component required college aged participants to rate perceptions of age and health in regards...

These variations often provide an insight into a listener’s perceptions of a speaker’s vocal characteristics and these perceptions may vary across settings. METHODS: This study required four components. The first component required college aged participants to rate perceptions of age and health in regards to young and old female vocalists. The second section required college aged participants to rate professionalism in regards to young and old female vocalists. Speech Professionals were asked to participate in the third component of this study, in which they rated listeners among the GRBAS scale. The last component required a quantification of results using a standard acoustic measure like cepstral peak prominence. RESULTS: Strong positive correlations were found between estimated age and actual age, strong negative correlations were found between older women and professionalism; moderately positive correlations were found between younger women and professionalism; moderate to strong correlation was found between age and GRBAS; and moderate negative correlations were found between age and CPPS. DISCUSSION: The following results were found: College-aged students were able to distinguish between the younger and older females. Older women were perceived as less professional. As age increases, GRBAS scores also increase. As age increases, CPPS ratings will decrease. CONCLUSION: Further research may require completion of surveys in a controlled environment, and inclusion of pitch-related measures as they relate to the workplace.
