This project is concerned with normal and abnormal speech production, mainly from biomechanical and neuromotor perspectives. The three studies elaborated are concerned with respiratory function and are a continuation of thematic research that has been conducted in our laboratory over more than two decades. For the studies proposed, non-invasive methods will be used. Study #1A will longitudinally and cross-sectionally investigate and document the nature of the refinement of speech breathing in young children and provide a data base against which young children with speech breathing disorders can be compared. Study #lB will longitudinally investigate and document the nature of the emergence of speech breathing in infants-children with neuromotor problems associated with cerebral palsy. It will make a direct contribution to our understanding of the salient features of the control problems involved and suggest implications for the evaluation and management of children with neuromotor impairments. Study #1C will investigate the interaction between speech breathing and ventilation in normal adults and provide a data base against which adults with various disorders can be compared. This study will elucidate the mechanisms involved in drive-to-speak versus drive-to-breathe factors and will shed light on how cognitive, chemical, and mechanical factors converge at the speech breathing-ventilation interface.

这个项目涉及正常和异常的言语产生， 主要是从生物力学和神经运动的角度。这三项研究 阐述了与呼吸功能有关的，是一个延续， 在我们的实验室进行的主题研究中， 超过二十年对于拟议的研究，将采用非侵入性方法， 采用研究#1A将进行纵向和横断面调查， 记录了年轻时语言呼吸的精致本质 儿童和提供一个数据库，对幼儿与语言 呼吸障碍可以比较。研究#1B将纵向 调查并记录语言呼吸出现的本质 在患有与大脑相关的神经运动问题的婴儿-儿童中， 麻痹它将直接有助于我们了解 所涉及的控制问题的突出特点和建议的影响 用于评估和管理神经运动障碍儿童。 研究#1C将研究言语呼吸和 在正常成人的通风，并提供一个数据库，对成年人 可以与各种疾病进行比较。这项研究将阐明 驱动说话与驱动呼吸因素的机制， 将揭示认知、化学和机械因素 汇聚在语音呼吸-通气界面。
