NORMAL AND ABNORMAL SPEECH PRODUCTION

这个项目涉及正常和异常的语音产生， 主要是从生物力学和神经运动的角度。三项研究 详述与呼吸功能有关，是一个续篇 在我们实验室进行的主题研究的更多 而不是二十年。对于拟议的研究，非侵入性方法将是 使用。研究#1a将纵向和横向调查和 记录青少年言语呼吸精炼的本质 并提供了一个数据库，供幼儿说话时参考 呼吸障碍可以被比作。研究报告#lb将纵向 调查并记录言语呼吸出现的本质 在婴儿-患有与大脑相关的神经运动问题的儿童中 瘫痪。这将直接有助于我们理解 所涉及的控制问题的显著特征和建议 用于评估和管理有神经运动障碍的儿童。 研究1C将调查语音呼吸和呼吸之间的相互作用 并提供了一个数据库，供成年人对照 可以与各种障碍进行比较。这项研究将阐明 驱使说话与驱使呼吸因素和 将阐明认知、化学和机械因素是如何 在语音呼吸-通风界面汇合。

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.
