The performances of younger adult (under age 40) and geriatric (over age 65) subjects were assessed on the following tasks: (a) maximum pitch range, (b) diado-chokinesis, (c) maximum vowel intensity, (d) maximum vowel duration, (e) maximum intraoral breath pressure, and (f) vital capacity. On all of these tasks the geriatric subjects showed reduced scores when compared with younger adults.
