In a previous study, children with cleft palate with hard palate closure at 12 months of age showed more typical phonological development than did children with an unrepaired hard palate at 36 months of age. This finding was based on narrow transcription of word initial target consonants obtained from a simple naming test. To evaluate the relevance of this finding, we investigated how well the children's target words were understood by 84 naive listeners.
A cross-sectional study.
Data obtained from 28 children with unilateral cleft lip and palate, 3 years of age, who received hard palate closure at either 12 months (hard palate repaired; HPR) or 36 months (hard palate unrepaired; HPU) were compared with data obtained from 14 age-matched, typically developing control children.
Video recordings of the children naming target words were shown to 84 naive listeners between 15 and 24 years of age who typed the word they heard.
The findings of this study indicated that naive listeners correctly identified a larger percentage of words in the control children followed by children in the HPR group. Children in the HPU group were more difficult for the naive listeners to understand. The error of retraction/backing of alveolar target consonants to velar place of articulation occurred frequently and most often in the HPU group and was found to have a negative effect on intelligibility.
在先前的一项研究中，12个月时硬腭闭合的腭裂患儿比36个月时硬腭未修复的患儿表现出更典型的语音发展。这一发现基于从简单命名测试中获得的单词首目标辅音的窄转录。为了评估这一发现的相关性，我们调查了84名未受过专业训练的听众对儿童目标单词的理解程度。
横断面研究。
从28名3岁单侧唇腭裂患儿中获取数据，这些患儿在12个月时接受了硬腭闭合手术（硬腭修复；HPR）或36个月时未接受手术（硬腭未修复；HPU），并将其与从14名年龄匹配、发育正常的对照儿童中获得的数据进行比较。
向84名年龄在15至24岁之间未受过专业训练的听众播放儿童命名目标单词的视频记录，他们将听到的单词打出来。
本研究结果表明，未受过专业训练的听众正确识别出对照儿童说出单词的百分比更高，其次是HPR组的儿童。HPU组的儿童对未受过专业训练的听众来说更难理解。齿龈目标辅音向软腭发音部位回缩/后缩的错误频繁发生，且最常出现在HPU组，并且发现这对可懂度有负面影响。
