The aim of the present study was to investigate relationships between characteristics of children's target words and their actual productions during the single-word period in American English. Word productions in spontaneous and functional speech from 18 children acquiring American English were analyzed. Consonant sequences in 3,328 consonant-vowel-consonant (CVC) target words were analyzed in terms of global place of articulation (labials, coronals, and dorsals). Children's actual productions of place sequences were compared between target words containing repeated place sequences (e.g., ) and target words containing variegated place sequences (e.g., ). Overall, when the target word contained two consonants at the same global place of articulation (e.g., labial-labial, ; coronal-coronal, ), approximately 50% of children's actual productions matched consonant place characteristics. Conversely, when the target word consisted of variegated place sequences (e.g., ), only about 20% of the productions matched the target consonant sequences. These results suggest that children's actual productions are influenced by their own production abilities as well as by the phonetic forms of target words.
本研究旨在探究美国英语单词语音发展阶段中儿童目标词汇特征与其实际产出之间的关系。通过分析 18 名正在习得美国英语的儿童自然语料和功能语料中的单词产出，我们对 3328 个由辅音-元音-辅音（CVC）组成的目标词汇中的辅音序列进行了整体发音位置（唇音、齿龈音和软腭音）分析。我们对比了包含重复发音位置序列（如，）和包含混合发音位置序列（如，）的目标词汇中，儿童实际产出的位置序列。总体来说，当目标词汇包含两个相同整体发音位置的辅音时（如，唇音-唇音，；齿龈音-齿龈音，），约有 50%的儿童实际产出与辅音位置特征相匹配。相反，当目标词汇包含混合发音位置序列时（如，），只有约 20%的产出与目标辅音序列相匹配。这些结果表明，儿童的实际产出既受到其自身产出能力的影响，也受到目标词汇语音形式的影响。
