DESCRIPTION (provided by applicant): How individuals who use two languages organize their phonetic system(s) has been of long-standing interest in the area of bilingual and second language (L2) speech research. Great attention has been paid to adult L2 learners, but few studies have characterized how phonetic categories emerge and develop in early acquisition and what kind of mechanisms are at play in this process in bilingual children. The main goal of this proposed study is to examine vowel and consonant production in Korean-English bilingual children in order to determine developmental patterns of speech production. In our preliminary studies, we have acoustically examined speech production in 5- and 10-year-old Korean-English bilingual children and found developmental differences between the two age groups. First, 5-year-old children established distinctive systems for each language for vowels but not for stop consonants, while 10-year-old children obtained distinctive systems for both vowels and consonants; second, both groups of children employed different underlying mechanisms. Based on these observations, we propose to further investigate speech production at two different chronological ages in order to determine more precise developmental patterns: 3- and 7-year-old children. Examination of bilingual children's speech will make significant contributions to the current literature of bilingualism in that the proposed study will allow us to explain the developmental processes by which bilingual speakers reach the level of fully established speech production. Furthermore, examining normally developing bilingual children will provide important educational and clinical implications for bilingual children with speech sound disorders. Without a clear understanding of the speech patterns in typically developing children learning two languages, it is difficult to implement speech assessment and intervention programs to serve linguistically diverse children with speech sound disorders. Thus, the results of this proposed study will provide significant information for developing speech assessment and intervention programs for bilingual children with speech sound disorders. PUBLIC HEALTH RELEVANCE: Examining speech production characteristics of normally developing bilingual children will provide important educational and clinical implications for bilingual children with speech sound disorders because the developmental speech patterns of normally developing children are commonly considered to be a diagnostic tool for speech disorders. Without a clear understanding of the speech patterns in typically developing children learning two languages, it is difficult to implement assessment and intervention programs to serve bilingual children with speech sound disorders. Thus, the results of this proposed study will provide significant information for developing speech assessment and intervention programs for bilingual children with speech sound disorders.

描述（由申请人提供）：使用两种语言组织语音系统的个人如何对双语和第二语言（L2）语音研究具有长期的兴趣。对成年L2学习者的关注非常关注，但是很少有研究表征语音类别在早期获取中如何出现和发展，以及在这一过程中在双语儿童中发挥了什么样的机制。这项拟议的研究的主要目标是检查韩国英语双语儿童的元音和辅音生产，以确定语音生产的发展模式。在我们的初步研究中，我们在5岁和10岁的韩国英语双语儿童中进行了声学检查，并发现了两个年龄段之间的发育差异。首先，5岁的孩子为元音建立了独特的系统，而不是停止辅音，而10岁的孩子则获得了元音和辅音的独特系统。其次，两组儿童都采用了不同的潜在机制。基于这些观察结果，我们建议在两个不同的年代年龄上进一步研究言语产生，以确定更精确的发育模式：3岁和7岁的儿童。对双语儿童言论的研究将为当前的双语文学做出重大贡献，因为拟议的研究将使我们能够解释双语说话者达到完全建立的语音生产水平的发展过程。此外，检查通常发展双语儿童将为言语障碍的双语儿童提供重要的教育和临床意义。如果没有清楚地了解典型的儿童学习两种语言的语音模式，就很难实施语音评估和干预计划，以服务于语言疾病的语言多样化的儿童。因此，这项拟议的研究的结果将为有声音疾病的双语儿童制定语音评估和干预计划提供重要信息。 公共卫生相关性：检查通常发展双语儿童的言语生产特征将为患有声音疾病的双语儿童提供重要的教育和临床意义，因为通常认为正常发育的儿童的发育语音模式通常被认为是言语障碍的诊断工具。如果没有清楚地了解典型的儿童学习两种语言的语音模式，就很难实施评估和干预计划来为双语儿童提供言语障碍。因此，这项拟议的研究的结果将为有声音疾病的双语儿童制定语音评估和干预计划提供重要信息。
