Age-related changes in human vocal tract configurations and the effects on speakers' vowel formant frequencies: A pilot study

摘要: The study aims to: (i) make accurate measurements of age-related changes in female speakers' vocal tract configurations with acoustic reflection technique (ART); (ii) obtain information vowel formant frequency as a function aging; and (iii) test the hypothesis that there are dimensional concomitant decreases all frequencies people age. Preliminary findings indicate older subjects tend to have more expanded pharyngeal lumen, but not longer length, than their younger cohorts, would unanimously decrease aging. highlights importance larger-scale configuration necessity developing new models will delineate other
