DESCRIPTION (provided by applicant): The purpose of the proposed project is to provide the candidate with additional career development training in the areas of spoken language development, speech sound disorders in children, and acoustic analysis, to enable the candidate to establish a productive research program geared towards the long-term goals of 1) advancing knowledge of typical development of spoken language production in terms of the various processing stages involved, 2) gaining a more detailed understanding of speech sound disorders in children that may result from disruptions at these processing stages, and 3) bridging the gap between basic science and clinical application. To achieve this purpose, the project includes both career development activities and a research plan designed to gain insight into the representations and real time processes involved in speech sound production in typically developing children as well as in children with speech sound disorders of unknown origin. Several experiments combine chronometric paradigms with speech acoustic analyses to address the emergence of speech planning units (e.g., phonemes) and their deployment in the speech planning process, as well as a number of factors that have been postulated to influence the emergence of these units (e.g., vocabulary size, speech motor skill). The proposed studies focus on children in the age range of 5 to 10 years old, because relatively little is known about speech development in this age range, despite the fact that development of speech production is not complete at age 5 and may affect literacy development. A major long-term goal of this research program is to increase our understanding of speech sound disorders of unknown origin, in particular with respect to the different planning stages affected in different types of disorders such as phonological disorders and childhood apraxia of speech. A combined chronometric-acoustic approach may enable a further delineation and differentiation among children with speech sound disorders, with implications for clinical service delivery for these children in terms of both diagnosis and treatment. PUBLIC HEALTH RELEVANCE: Children with speech sound disorders of unknown origin comprise a large part of the clinical caseload for speech-language pathologists. A complete understanding of the nature of these disorders is lacking, complicating differential diagnosis and treatment. This research will enhance our understanding of typical and atypical development of speech planning and production, with implications for diagnosis and treatment.

描述（由申请人提供）：拟议项目的目的是为候选人提供口语发展领域的其他职业发展培训，言语疾病，儿童的声音障碍和声学分析，使候选人能够建立一项针对长期的生产性研究计划，以实现长期的目标1）提高言语的典型范围，以了解各种言论的典型发展，以了解各种言论的言论，以了解各种言论的范围，以了解众所周知的2），以了解涉及的言论，以了解涉及的各种详细的范围，以了解一项详细信息，以了解一项典型的言论，以了解一项详细信息，该言论的范围是涉及的2）。在这些处理阶段的破坏，以及3）弥合基础科学和临床应用之间的差距。为了实现这一目的，该项目既包括职业发展活动，又包括一项研究计划，旨在深入了解典型发展中的儿童以及具有未知来源的言语疾病的儿童中言语声音生产所涉及的表示和实时过程。几项实验将计时范式与语音声学分析相结合，以解决语音计划单元（例如音素）的出现及其在语音计划过程中的部署，以及已经假定的许多因素会影响这些单元的出现（例如，词汇大小，语音运动技能，语音运动技能）。拟议的研究集中于5至10岁年龄段的儿童，因为对于该年龄范围内的语音发展知之甚少，尽管言语产生的发展在5岁时并不完整，并且可能影响扫盲的发展。该研究计划的一个主要长期目标是增加我们对未知来源的语音疾病的理解，特别是在不同类型的疾病（例如语音障碍和言语儿童失差）中受影响的不同计划阶段。综合时间表声学方法可以使言语障碍儿童进行进一步的描述和分化，这对这些儿童的诊断和治疗都对临床服务的影响产生影响。 公共卫生相关性：未知来源的言语疾病的儿童构成了言语病理学家临床案件的很大一部分。缺乏对这些疾病的性质的完全了解，使鉴别诊断和治疗变得复杂。这项研究将增强我们对语音计划和生产的典型和非典型发展的理解，对诊断和治疗产生影响。
