This article provides a brief review of age-related changes in speech production before discussing fluency changes that have been found in aging, nonstuttering speakers. Most studies agree that old and young adults evidence similar frequencies of disfluency. The disfluencies of a 105-year-old woman were compared to the means of several geriatric groups whose average ages were more than 20 years younger. Overall frequencies and types were similar. Thus, aging speakers' fluency does not appear to be more susceptible to breakdowns than that of younger speakers, although there is some evidence that elderly speakers become much more disfluent than younger speakers under stressful conditions.
本文在讨论老年非口吃者言语流畅性变化之前，简要回顾了与年龄相关的言语产生变化。大多数研究一致认为，老年人和年轻人出现言语不流畅的频率相似。将一位105岁女性的言语不流畅情况与几个平均年龄比她小20多岁的老年人群体的均值进行了比较。总体频率和类型相似。因此，尽管有证据表明老年人在压力条件下比年轻人更容易出现言语不流畅，但老年说话者的言语流畅性似乎并不比年轻说话者更容易出现障碍。
