This study reports data on vocal fundamental frequency (f) and the first four formant frequencies (F1, F2, F3, F4) for four vowels produced by speakers in three adult age cohorts, in a test of the null hypothesis that there are no age-related changes in these variables. Participants were 43 men and 53 women between the ages of 20 and 92 years.
The most consistent age-related effect was a decrease in f for women. Significant differences in F1, F2, and F3 were vowel-specific for both sexes. No significant differences were observed for the highest formant F4.
Women experience a significant decrease in f, which is likely related to menopause. Formant frequencies of the corner vowels change little across several decades of adult life, either because physiological aging has small effects on these variables or because individuals compensate for age-related changes in anatomy and physiology.
本研究报告了三个成年年龄组的 speakers 发出的四个元音的语音基频（f）和前四个共振峰频率（F1、F2、F3、F4）的数据，以检验这些变量不存在与年龄相关变化的零假设。参与者为43名男性和53名年龄在20至92岁之间的女性。
最一致的与年龄相关的效应是女性的f下降。F1、F2和F3的显著差异在两性中都是特定于元音的。对于最高共振峰F4，未观察到显著差异。
女性的f显著下降，这可能与更年期有关。在成年后的几十年里，角元音的共振峰频率变化很小，要么是因为生理衰老对这些变量的影响很小，要么是因为个体补偿了解剖学和生理学上与年龄相关的变化。
