Reference data for the acoustic vowel space area (VSA) in children and adolescents do not currently appear to be available in a form suitable for normative comparisons. In the current study, individual speaker formant data for the four corner vowels of American English (/i, u, æ, ɑ/) were used to compute individual speaker VSAs. The sample included 300 children aged 5-18 years and 38 adults aged 25-50 years. Age trends and sex differences were examined and reference data for clinical application were developed. Findings indicated significant declines in VSA with age; sex differences were not fully apparent until late adolescence and adulthood. Implications are discussed.
目前似乎没有以适合进行规范性比较的形式提供儿童和青少年声学元音空间区域（VSA）的参考数据。在本研究中，使用美式英语四个角元音（/i, u, æ, ɑ/）的个体发音人共振峰数据来计算个体发音人的VSA。样本包括300名5至18岁的儿童和38名25至50岁的成年人。研究了年龄趋势和性别差异，并制定了临床应用的参考数据。研究结果表明，VSA随年龄显著下降；性别差异直到青春期后期和成年期才完全显现。对研究结果的意义进行了讨论。
