Fundamental frequency (Fo) and jitter were measured in digitized live-voice productions of sustained vowels [a], [i], and [u] from women, men, and 6- through 9-year-old children. Results showed (a) significant developmental differences for mean Fo and for the pattern of jitter by vowel type, (b) significant gender differences in Fo and jitter only for adults, (c) significant differences in Fo and jitter according to vowel type for all subjects, and (d) similar amounts of mean absolute jitter for children and women for all vowels with nonsignificantly different values of jitter for boys and men on [i] and [u] productions. Results are related to Honda's theory of intrinsic Fo for vowels and to Titze's neurologic model of jitter.
对女性、男性以及6至9岁儿童在持续发元音[a]、[i]和[u]时的数字化现场语音进行了基频(Fo)和抖动测量。结果显示:(a)平均Fo以及元音类型引起的抖动模式存在显著的发育差异;(b)仅在成年人中,Fo和抖动存在显著的性别差异;(c)所有受试者的Fo和抖动根据元音类型存在显著差异;(d)所有元音中,儿童和女性的平均绝对抖动量相似,在发[i]和[u]时,男孩和男性的抖动值差异不显著。这些结果与本田的元音固有Fo理论以及蒂茨的抖动神经学模型相关。
