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(More)
The older speaker's production of phonology is affected by physiological and anatomic changes that occur with age. The differences in phonatory performance between a group of 20 young adults (aged 21 to 32) and 20 older adults (aged 68 to 82) were measured in the articulatory rate dimension. Spectrographic measurement revealed that older adults produced(More)
Fundamental frequency variations were examined in readings of the fourth and fifth sentences of the "Rainbow Passage" and in the sustained vowel /a/ produced by 20 young adults and 20 older adults. The Tektronix Visipitch provided the fundamental frequency contour (frequency variations in continuous reading) and Honeywell Visicorder determined frequency(More)
16 women and 16 men as listeners provided magnitude estimation scaling responses for the intelligibility and acceptability of synthesized speech transmitted by two different individuals using a voice output communication aid (VOCA). Listeners rated the samples when presented by a physically disabled nonspeaking male and when presented by a nondisabled(More)
Effects of gender on listeners' judgments of intelligibility were investigated. Subjects (15 women; 15 men) provided magnitude-estimation scaling responses and over-all impression of the intelligibility of a male and female speaker's comparable versions of audiotaped speech samples varying systematically in terms of the number of phonemes produced(More)
