本研究探讨了儿童和青少年时期元音空间区（VSA）的发育及其对高发音元音能力的影响。在实验1中，96名9-14岁的参与者在沟通容易（无障碍，“NB”）和困难（一个参与者的讲话通过声码器“VOC”过滤）的情况下进行互动任务。先前20名成人的记录作为参考。测量VSA （ERB2）、F1、F2范围（ERB）及关节率。儿童的VSA明显大于成人。从11岁开始，VOC的元音高发音明显，但这只是因为NB的VSA随着年龄的增长而逐渐减少。结果表明，虽然大的VSA并不能阻止儿童过度发音，但实现这一目标的方式可能与成人不同。实验2是为了验证大的VSA不是孩子们看不见彼此的副产品。13名参与者与对话者面对面进行同样的任务。与实验1中匹配的参与者相比，VSA没有差异，表明仅音频模式不影响结果。讨论了儿童和青少年自发言语中VSA较大的可能原因。
This study investigated vowel space area (VSA) development in childhood and adolescence and its impact on the ability to hyperarticulate vowels. In experiment 1, 96 participants aged 9–14 years carried out an interactive task when communication was easy (no barrier, ‘NB’) and difficult (the speech of one participant was filtered through a vocoder, ‘VOC’). Previous recordings from 20 adults were used as reference. Measures of VSA (ERB2), F1 and F2 ranges (ERB) and articulation rate were obtained. Children's VSA were significantly larger than adults'. From the age of 11, vowel hyperarticulation was evident in VOC, but only because VSA were gradually reducing with age in NB. The results suggest that whilst large VSA do not prevent children from hyperarticulating vowels, the manner in which this is achieved may not be adult-like. Experiment 2 was conducted to verify that large VSA were not a by-product of children being unable to see each other. Thirteen participants carried out the same task face-to-face with their interlocutor. Comparisons to matched participants from experiment 1 showed no differences in VSA, indicating that the audio-only modality did not influence results. Possible reasons for larger VSA in the spontaneous speech of children and adolescents are discussed.
