Listeners' identification of young children's productions of minimally contrastive words and predictive relationships between accurately identified words and intelligibility scores obtained from a 100-word spontaneous speech sample were determined for 36 children with typically developing speech (TDS) and 36 children with speech sound disorders (SSD) of unknown origin in three age groups (3+, 4+ and 5+ years). Each child's productions of 78-word stimuli were recorded and presented to unfamiliar adults for forced-choice identification. Results of a two-way MANOVA (two groups by three ages) indicated that the TDS group had significantly higher (p < 0.001) percent consonant items correct (PCIC) and percent syllable shape items correct. Stepwise regression analyses revealed significant predictors of intelligibility scores to be PCIC (adjusted R(2) = 0.10, p = 0.04) for the TDS group and PCIC and percent vowel items correct (adjusted R(2) = 0.63, p < 0.001) for the SSD group.
针对36名发育正常的儿童（TDS）和36名病因不明的语音障碍儿童（SSD），分三个年龄组（3岁以上、4岁以上和5岁以上），确定了听众对幼儿发出的最小对比词的识别情况，以及准确识别的单词与从100个单词的自发语音样本中获得的可懂度分数之间的预测关系。记录了每个孩子对78个单词刺激的发音，并将其呈现给不熟悉的成年人进行强制选择识别。双向多变量方差分析（两组×三个年龄）结果表明，TDS组的辅音项目正确百分比（PCIC）和音节形状项目正确百分比显著更高（p < 0.001）。逐步回归分析显示，对于TDS组，可懂度分数的显著预测因素是PCIC（调整后R(2) = 0.10，p = 0.04）；对于SSD组，可懂度分数的显著预测因素是PCIC和元音项目正确百分比（调整后R(2) = 0.63，p < 0.001）。
