Disfluency and rate characteristics of a young adult group (21-30 years) and two groups of middle-aged (45-54 and 55-64 years, respectively) and two groups of older males (65-74 and 75-91 years, respectively) were investigated to determine whether there were significant differences among groups as reflected by two rate and seven disfluency measures during oral reading, picture description, and conversational speech. Findings revealed that speech rate during each of the speaking tasks differed significantly among young adult, middle-aged, and older males. Also, speech rate differed significantly, in decreasing order, for oral reading, conversation, and picture description, irrespective of age. Levels of disfluency, however, did not appear to differ among the various age groups.
研究了一个年轻成年组（21至30岁）、两组中年男性（分别为45至54岁和55至64岁）以及两组老年男性（分别为65至74岁和75至91岁）的言语不流畅性和语速特征，以确定在朗读、图片描述和对话言语过程中，两组语速和七种言语不流畅性指标所反映的组间是否存在显著差异。研究结果显示，在每项言语任务中，年轻成年男性、中年男性和老年男性的语速存在显著差异。此外，无论年龄如何，朗读、对话和图片描述的语速也存在显著差异，且依次递减。然而，不同年龄组之间的言语不流畅水平似乎没有差异。
