The overarching long-term objective of my research program is to investigate the development of speech production-perception relationships in children. In the last five decades, it has been claimed that multiple sources of sensory feedback are used to monitor the speech articulators, the most important of which is auditory feedback. From a developmental perspective, auditory feedback is crucial to acquire the appropriate articulatory positions related to vowels and consonants. Although many studies have been conducted on the role of feedback in speech production, none has addressed this issue in children, using original data on articulatory movements, acoustic parameters, and perceptual measures.***For the next five years, the global objective of my research program is to study the role of auditory feedback in speech production using the sensory perturbation paradigm in preschool- and school-aged children. To this end, the three specific objectives of this proposal are (a) to study the development of perceptual auditory acuity in relation with the produced vowel categories, (b) to study the articulatory and acoustic strategies children and adults use to adapt to altered auditory feedback within and across vowel categories, and (c) to determine which adaptation strategies are the most perceptually relevant. To achieve these objectives, we propose to make kinematic and acoustic recordings of speech sequences produced by typically developing children and by adults. Perceptual tests will also be conducted and the results will be compared to the produced data.***The innovative nature of this research program resides primarily in the problem addressed: while the impact of sensory perception on the development of speech has been the subject of numerous studies, none has focused on an integrated articulatory and acoustic analysis of strategies to compensate for altered auditory feedback, taking into account the individual's global vowel space. Furthermore, our proposed method, combining infrared motion capture and ultrasound imaging, is unique. Our research program will lead to groundbreaking advances in the area of sensorimotor development in speech, and will contribute to the development of innovative technological tools. Indeed, by providing original data on the interaction of sound categories and speech perception in children, our program will allow us to consolidate and expand our collaborations with vocal technology companies to develop virtual growing talking heads designed to improve second language learning. Our proposed research program will also create a research environment conducive to the training of highly qualified personnel (undergraduate and graduate students and postdoctoral fellows) in the area of oral language processing.**

我的研究计划的总体长期目标是调查儿童言语产生与感知关系的发展。在过去的五年里，有人声称使用多种感觉反馈源来监测发音器官，其中最重要的是听觉反馈。从发育的角度来看，听觉反馈对于获得与元音和辅音相关的适当发音位置至关重要。尽管已经针对反馈在言语产生中的作用进行了许多研究，但没有一项研究使用关于发音运动、声学参数和知觉测量的原始数据来解决儿童中的这个问题。***在接下来的五年中，我的研究计划的全球目标是使用学龄前和学龄儿童的感觉扰动范式来研究听觉反馈在言语产生中的作用。为此，该提案的三个具体目标是（a）研究与产生的元音类别相关的感知听觉敏锐度的发展，（b）研究儿童和成人用于适应元音类别内和元音类别之间改变的听觉反馈的发音和声学策略，以及（c）确定哪些适应策略在感知上最相关。为了实现这些目标，我们建议对典型发育中的儿童和成人产生的语音序列进行运动学和声学记录。还将进行感知测试，并将结果与​​产生的数据进行比较。***该研究计划的创新性主要在于所解决的问题：虽然感官知觉对言语发展的影响一直是众多研究的主题，但没有一项研究侧重于对补偿改变的听觉反馈的策略进行综合发音和声学分析，同时考虑到个人的整体元音空间。此外，我们提出的方法结合了红外运动捕捉和超声成像，是独一无二的。我们的研究计划将在言语感觉运动发展领域带来突破性进展，并将为创新技术工具的开发做出贡献。事实上，通过提供有关儿童声音类别和言语感知相互作用的原始数据，我们的计划将使我们能够巩固和扩大与声音技术公司的合作，开发旨在改善第二语言学习的虚拟成长说话头。我们提出的研究计划还将创造一个有利于口语处理领域高素质人才（本科生、研究生和博士后）培训的研究环境。 **
