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.

老年人声音的常见感知特征包括声音嘶哑、气息声、不稳定以及音高变化。尽管已有关于老年人声音变化的研究，但很少有研究探讨声音质量感知与声学指标之间的关系。本研究的目的是考察感知到的气息声和嘶哑与选定声学变量之间的关系。研究结果显示，在基频标准差、幅度微扰商和噪声谐波比方面存在显著的年龄相关差异。在年轻和老年说话者之间，感知到的嘶哑程度没有显著差异。然而，年轻女性被认为比老年女性的气息声明显更重。在嘶哑和气息声的感知与声学指标之间发现了中度相关性。这些发现结合可能导致衰老感知的与年龄相关的喉部变化进行了讨论。
