ABSTRACT
A number of changes in older adults' speech characteristics accompany aging. This article reviews the changes usually perceived in elders' speech, then focuses on several key components of older adults' speech that account for these changes: vowel productions, voice onset time and phoneme segment duration, and speaking rate. Although laryngeal factors are evident in older voices and associated with declining physiological conditions, certain changes are associated with advanced age.
KEY WORDS
