Formant Frequency Characteristics of Children, Young Adult, and Aged Female Speakers

Abstract

Previous literature indicates that a difference may exist between formant frequencies (F 1 and F 2 ) of children, young adult, and elderly speakers. The purpose of this study was to compare F 1 and F 2 of 3 young, 6 young adult, and 3 elderly female speakers for the /i/, /æ/, /u/, and /a/ vowels. Analysis indicates a trend towards vowel reduction across the life span. These findings support previous research regarding age-associated acoustic changes as well as support for the possible anatomical and physiological alterations which may influence such changes.
