Effects of Aging on Speech and Voice

Abstract

The primary purpose of this paper is to examine age-related changes in the mechanisms associated with two major components of communication: speech and voice. A secondary purpose is to discuss the impact of these changes on nonspeech functions (e.g., chewing and swallowing) associated with the orofacial mechanism (the same mechanism involved in articulation of sounds and syllables). Central to these perspectives is a focus on communication behavior as a critical tool for the older adult in the process of life adjustment. Knowledge of gerontological communication behaviors is important to physical therapists, occupational therapists and other professionals who must maximize successful communication with older clients.
