近年来，人们越来越关注语音发育和语音障碍中的元音，但语音障碍儿童中元音错误的发生率尚未确定。在本研究中，我们测量了314名单语美国英语儿童的单字发音中非卷舌元音正确率（PVC - NR）的百分比，其中165名是正常音系（NP）儿童，149名是延迟/无序音系（DP）儿童。使用三个截止值（PVC‐NR <85、<90和<95）来确定元音错误的发生率。较年轻的NP儿童（18至35个月大）表现出元音错误的百分比很高（24%至65%，取决于所使用的截止日期），但随着年龄的增长而下降。较大NP患儿（≥36个月）元音错误发生率最低（0 - 4%）。在DP组（30 ~ 81个月）中，11% ~ 32%出现元音错误。中度至重度辅音错误的DP儿童并发元音错误的风险最大。
Attention to vowels in phonological development and disorders has increased in recent years, but the incidence of vowel errors in children with phonological disorders has not yet been determined. In the present study, percentage of non‐rhotic vowels correct (PVC‐NR) was measured in single word productions of 314 monolingual American English‐speaking children, 165 with normal phonology (NP) and 149 with delayed/disordered phonology (DP). Three cutoffs (PVC‐NR <85, <90 and <95) were used to determine incidence of vowel errors. The percentage of younger NP children (18 to 35 months of age) exhibiting vowel errors was high (24 to 65%, depending on the cutoff used), but decreased with age. Incidence of vowel errors in older NP children (≥36 months) was minimal (0 to 4%). In the DP group (age range 30 to 81 months), 11 to 32% exhibited vowel errors. DP children with moderate to severe consonant errors were at greatest risk for concurrent vowel errors.
