目的本研究调查了植入人工耳蜗 (CI) 的双语西班牙语-英语儿童和单语英语儿童 (CI) 与听力正常的双语和单语同龄人 (NH) 的辅音和元音准确性以及整个单词的变异性（也称为词元间变异性或词元间不一致）。方法 参与者为 40 名年龄在 4;6 至 7;11（年；月；Mage= 6;2),n= 10，分为 4 个参与者组：带 CI 的西班牙语-英语双语组、带 CI 的单语英语组、带 NH 的西班牙语-英语双语组和带 NH 的单语英语组。生成了由 20 个不同长度的单词组成的西班牙语和英语单词列表，并对每个单词的 3 个产生式进行了分析，以了解辅音正确百分比、元音正确百分比以及是否存在任何辅音和/或元音变异性。结果与患有 NH 的同龄人相比，患有 CI 的儿童表现出较低的准确性和更多的全词变异性。听力状态匹配的双语儿童和单语儿童之间的准确率或全词变异率没有差异，并且双语儿童英语的准确度较低，全词变异率高于西班牙语。结论即使在有多年的 CI 经验后，CI 儿童的言语中全词变异率也很高，而且双语接触似乎不会对 CI 儿童的语音发育产生负面影响。讨论了对我们理解语音产生变异性的潜在来源和临床意义的贡献。
PurposeThis study investigates consonant and vowel accuracy and whole-word variability (also calledtoken-to-token variabilityortoken-to-token inconsistency) in bilingual Spanish–English and monolingual English-speaking children with cochlear implants (CIs) compared to their bilingual and monolingual peers with normal hearing (NH).MethodParticipants were 40 children between 4;6 and 7;11 (years;months;Mage= 6;2),n= 10 each in 4 participant groups: bilingual Spanish–English with CIs, monolingual English with CIs, bilingual Spanish–English with NH, and monolingual English with NH. Spanish and English word lists consisting of 20 words of varying length were generated, and 3 productions of each word were analyzed for percent consonants correct, percent vowels correct, and the presence of any consonant and/or vowel variability.ResultsChildren with CIs demonstrated lower accuracy and more whole-word variability than their peers with NH. There were no differences in rates of accuracy or whole-word variability between bilingual and monolingual children matched on hearing status, and bilingual children had lower accuracy and greater whole-word variability in English than in Spanish.ConclusionsHigh rates of whole-word variability are prevalent in the speech of children with CIs even after many years of CI experience, and bilingual language exposure does not appear to negatively impact phonological development in children with CIs. Contributions to our understanding of underlying sources of speech production variability and clinical implications are discussed.
