Formant frequency characteristics of children, young adult, and aged female speakers.
Previous literature indicates that a difference may exist between formant frequencies (F1 and F2) of children, young adult, and elderly speakers. The purpose of this study was to compare F1 and F2 of 3 young, 6 young adult, and 3 elderly female speakers for the /i/, /ae/, /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.
