Abstract

Word complexity indices, such as the Index of Phonetic Complexity (IPC) and the Word Complexity Measure (WCM), code a word in terms of featural and structural properties that pose difficulty in phonological development. Studies have investigated the influence of complexity indices on vocabulary development; however, few have examined their influence on consonant accuracy. Furthermore, these indices were developed for English-speaking children and have not been widely applied to other languages. This study investigates whether a word's phonological complexity influences how accurately it is produced in French-speaking children. Four databases consisting of the productions of children (n = 74), aged 1;11 to 4;9, were analyzed. Words were coded in terms of the IPC, WCM, and parameters that add complexity during phonological development. Using mixed-effects logistic regression, we examined whether phonological complexity as determined by the IPC, WCM, or by alternative indices better accounts for the influence of complexity on production. We also investigated whether the accuracy of a target sound/structure was influenced by a word's complexity. Results indicated that complexity based on the IPC or WCM significantly influenced consonant accuracy; however, indices tapping fewer features provided superior model fit. At younger ages, the presence of fricatives/liquids and, at all ages, the presence of alveopalatal fricatives, codas, and clusters significantly influenced accuracy. Findings were inconclusive as to whether whole word complexity influenced the accuracy of a target sound/structure. Results suggest that current complexity indices provide only approximate indications of how featural and structural properties of words influence production.

语音复杂性对法语儿童造词能力的影响
单词复杂性指数,如语音复杂性指数(IPC)和单词复杂性测量(WCM),根据给语音发展带来困难的特征和结构特性对单词进行编码。已有研究调查了复杂性指数对词汇发展的影响,但很少研究它们对辅音准确性的影响。此外,这些指数都是针对英语儿童开发的,尚未广泛应用于其他语言。本研究探讨了单词的语音复杂程度是否会影响法语儿童发音的准确性。研究分析了四个数据库中 1;11 到 4;9 岁儿童(n = 74)的发音。根据 IPC、WCM 和在语音发展过程中增加复杂性的参数对单词进行了编码。通过混合效应逻辑回归,我们研究了由 IPC、WCM 或其他指数决定的语音复杂性是否能更好地解释复杂性对发音的影响。我们还研究了目标音/结构的准确性是否受单词复杂性的影响。结果表明,基于 IPC 或 WCM 的复杂度会显著影响辅音的准确性;然而,采用较少特征的指数能提供更好的模型拟合效果。在较小的年龄段,摩擦音/液音的存在,以及在所有年龄段,齿龈摩擦音、密码音和音群的存在都会对准确性产生显著影响。至于整个单词的复杂程度是否会影响目标音/结构的准确性,研究结果尚无定论。研究结果表明,目前的复杂度指数只能大致说明词语的特征和结构特性对发音的影响。
