title: The effect of age and vocal task on cepstral/spectral measures of vocal function in adult males.
abstract: This study investigated the effect of aging on cepstral/spectral acoustic measures calculated from clinical stimuli (vowels and sentences from the Consensus Auditory Perceptual Evaluation of Voice). Thirty younger adult males (20-49 years of age) and thirty older males (50-79 years of age) produced sustained vowels and read a connected speech stimulus which were applied to cepstral/spectral acoustic analyses to derive the multiparametric measure of Cepstral/Spectral Index of Dysphonia (CSID). Results indicated that older males exhibited significantly greater CSID measures than younger males in connected speech (p=0.001; d=0.98), but not the vowel. Linear regression revealed a moderate correlation between age and CSID in connected speech. These results further inform our understanding of how aging influences voice production in varied contexts and how commonly utilised clinical voice tasks subjected to cepstral/spectral acoustic analyses might differentially inform our knowledge of underlying vocal physiology.
