This investigation was designed to determine if velopharyngeal function during speech production, as reflected in measures of nasal air flow, differs with age in adults. Eighty subjects were studied, 40 women and 40 men, representing four age groups (20-30, 40-50, 60-70, and 80 + years). Results showed no age-related differences in nasal air flow. Sex-related differences in flow were found on productions of nasal consonants only. These findings do not support the suggestion of Hutchinson, Robinson, and Nerbonne (1978) that velopharyngeal function deteriorates with age.
本研究旨在确定在言语产生过程中，软腭咽功能（通过鼻气流测量反映）在成年人中是否随年龄而有所不同。研究了80名受试者，其中40名女性和40名男性，代表四个年龄组（20 - 30岁、40 - 50岁、60 - 70岁和80岁以上）。结果显示鼻气流方面不存在与年龄相关的差异。仅在鼻辅音发音时发现了与性别相关的气流差异。这些发现不支持哈钦森、罗宾逊和内尔博纳（1978年）提出的软腭咽功能随年龄恶化的观点。
