Sometimes, children's speech is judged as typical on picture-naming tests and not on other speech tests, even other picture-naming tests. This study attempts to explain this observation by examining the impact of increasing the numbers of polysyllabic words in a picture-naming test on the outcomes of percentages of consonants and vowels correct and phonological processes.
The participants were 283 randomly sampled, typically-developing children, aged 3-7-years. These Australian English speakers named pictures, yielding ∼166 selected words, varied for syllable number, stress and shape, which repeatedly sampled all consonants and vowels of Australian English.
Most mismatches occurred in di- and polysyllabic words, with few in monosyllabic words: the usual words in picture-naming speech tests. Significant age effects existed for percentages of consonants and vowels correct and for 12 of the 16 phonological processes investigated. Many age effects were present at 7 years; later than often reported.
These findings imply that additional di- and polysyllabic words add value to routine speech testing. Further, children, especially school children, who "pass" speech tests dominated by monosyllabic words may benefit from further examination of their productions of di- and polysyllabic words before finalizing clinical judgements about their speech status.
有时，儿童在图片命名测试中的言语表现被判定为正常，但在其他言语测试中却并非如此，甚至在其他图片命名测试中也是如此。本研究试图通过考察在图片命名测试中增加多音节词数量对辅音和元音正确百分比以及语音过程结果的影响来解释这一现象。
参与者为283名随机抽取的3至7岁发育正常的儿童。这些说澳大利亚英语的儿童对图片进行命名，产生了约166个选定的单词，这些单词在音节数量、重音和形状方面各不相同，反复抽取了澳大利亚英语的所有辅音和元音。
大多数不匹配情况出现在双音节和多音节词中，单音节词中较少：图片命名言语测试中的常见词汇。辅音和元音正确百分比以及所调查的16种语音过程中的12种存在显著的年龄效应。许多年龄效应在7岁时出现；比通常报道的时间晚。
这些发现表明，增加双音节和多音节词对常规言语测试有价值。此外，在对儿童言语状况做出最终临床判断之前，那些在以单音节词为主的言语测试中“通过”的儿童，尤其是学龄儿童，可能会从进一步检查他们双音节和多音节词的发音中受益。
