Purpose The purpose of the present investigation was to examine acoustic voice changes
across the life span. Previous voice production investigations used small numbers of …

This paper presents a longitudinal analysis of the extent to which age affects F0 and formant
frequencies. Five speakers at two time intervals showed a clear effect for F0 and F1 but no …

This study investigates prosodic planning in a reading task in German. We analyse how the
utterance length and syntactic complexity of an upcoming sentence affect two acoustic …

Vocal communication is negatively affected by neurodegenerative diseases, such as
Parkinson disease, and by aging. The neurological and sensorimotor mechanisms …

The manner and extent to which voice amplitude and frequency control mechanisms change
with age is not well understood. The related question of whether the assessment of one's …

Age-related reductions in pulmonary elastic recoil and respiratory muscle strength can affect
how older adults generate subglottal pressure required for speech production. The present …

Summary Background and Objective The effects of presbyphonia are compounded by the
decline in respiratory function that occurs with age. Commonly recommended exercises to …

Purpose The human voice qualitatively changes across the lifespan. Although some of these
vocal changes may be pathologic, other changes likely reflect natural physiological aging …

The study investigated the speech adaptations by older adults (OA) with and without age-
related hearing loss made to communicate effectively in challenging communicative …

Background: During aging, changes in human speech may arise because of the
neurophysiological deterioration associated with age, or as the result of an impairment in the …
