    Journal: J Commun Disord; 2006; 39(3):171-84. PubMed ID: 16360669.
    Abstract:
    UNLABELLED: Common perceptual characteristics of the elderly voice include hoarseness, breathiness, instability, and a change in the pitch of the voice. Although research is available concerning changes in the elderly voice, little research has been completed to examine the relationship between the perception of voice quality and acoustic measures. The purpose of this study was to examine the relationship between perceived breathiness and hoarseness and selected acoustic variables. The results of the study revealed significant age-related differences in fundamental frequency standard deviation, amplitude perturbation quotient, and noise-to-harmonic ratio. No significant difference in perceived hoarseness was found between the young and elderly speakers. However, the young women were perceived as significantly more breathy than the elderly women. Moderate correlations were found between the perceptions of hoarseness and breathiness and the acoustic measures. These findings are discussed relative to age-related laryngeal changes that may contribute to the perception of aging. LEARNING OUTCOMES: (1) To understand the perceptual attributes of the aging voice in men and women. (2) To understand the relation between the perception of voice quality and acoustic measures of voice production in the aging voice.
