The present study investigated the effects of selected measures of language experience (parent-reported estimates of frequency of output and language use) and language ability (parent-reported language proficiency and mean length of utterance in words) on the segmental accuracy of Spanish- and English-speaking bilingual children.
The phonological skills of 50 typically developing bilingual Spanish-English children (mean age = 5;9 [years;months]) were examined. Independent variables included parent estimates of language use, language proficiency, and frequency of language output (5 groups), as well as a direct language measure (mean length of utterance in words) to predict the dependent segmental accuracy measures (percentage of consonants and vowels correct).
Frequency of language output did not have an effect on any of the English or Spanish segmental accuracy measures. However, parent-reported language use and language proficiency as well as the direct measure of language ability (mean length of utterance in words) had various effects on segmental accuracy. Those effects differed, however, in language-specific patterns.
Parental estimates of language use and language proficiency are useful for predicting the phonological skills of bilingual Spanish- and English-speaking children, and augmenting them with a direct measure of language ability as a predictor of segmental accuracy is desirable.
本研究旨在探讨语言经验（父母报告的输出频率和语言使用估计）和语言能力（父母报告的语言熟练程度和话语中单词的平均长度）的几个测量指标对西班牙语和英语双语儿童的音段准确性的影响。
对 50 名发育正常的双语西班牙语-英语儿童（平均年龄=5；9[岁；月]）的语音技能进行了检查。自变量包括父母对语言使用、语言熟练程度和语言输出频率（5 组）的估计，以及直接语言测量（话语中单词的平均长度），以预测依赖的音段准确性测量（辅音和元音的正确百分比）。
语言输出频率对任何英语或西班牙语音段准确性测量均无影响。然而，父母报告的语言使用和语言熟练程度以及语言能力的直接测量（话语中单词的平均长度）对音段准确性有不同的影响。然而，这些影响在语言特异性模式上有所不同。
父母对语言使用和语言熟练程度的估计对预测双语西班牙语和英语儿童的语音技能很有用，并且最好用语言能力的直接测量作为音段准确性的预测指标来补充这些估计。
