Abstract
Acoustic and perceptual research has shown that an individual's vocal characteristics change with age. In this paper, we report a later-life longitudinal investigation of three male speakers using publicly available archives of speeches given to large audiences on a semi-regular basis (generally with a couple of years between each instance). The collection of speeches was given during the last 40-50 years of each speaker's life. From each speech, 5-minute samples (recordings and transcripts) were force-aligned to identify word and phoneme boundaries. We investigate non-linear changes in vowel duration, word duration, speech rate, fundamental frequency, and vowel space using Generalized Additive Mixed Models. We describe the vocal changes over the lifespan in the speakers' later years. The current results do not support expected outcomes from previous research and illustrate idiosyncratic and dynamic effects for individuals in later years.
