The two broad objectives of the current proposal are (a) to understand the potential relationship between speech breathing and articulation in persons with motor speech disorders, and (b) to develop a statistical model of articulatory variability in persons with motor speech disorders, and to use this model to explain the basis of speech motor control deficits in this population. More specifically, the aims of the proposed studies are (a) to understand how modifications in the starting lung volume for speech affect acoustical and perceptual measures of articulatory behavior, (b)to determine if persons with motor speech disorders are able to learn consistent modification of their starting lung volumes for speech, and (c) to study the statistical relationships between spectral and temporal properties of formant transitions produced by persons with motor speech disorders. The experimental plan to address these aims includes natural observation of the covariation between lung volume variables and the acoustical/perceptual measures mentioned above, single-case design methods to evaluate patients' ability to learn the lung volume modifications, and a paradigm in which speaking rate is intentionally varied for the purpose of inducing variability in articulatory processes. When the specific aims identified above are met, there should be a much better understanding of the factors contributing to communication deficits in persons with neurological disease, and hence a better notion of how best to treat the deficit.

本建议的两大目标是：（a）了解 语音呼吸和发音之间的潜在关系 患有运动性言语障碍的人，以及（B）开发统计学 运动性言语障碍患者的发音变异模型， 并用这个模型来解释语言运动控制的基础 这一人群中的赤字。更具体地说，拟议的 研究是（a）了解起始肺中的修饰 语音影响的声学和感知测量的音量 发音行为，（B）以确定具有运动言语的人是否 疾病能够学习他们的起始肺的一致修改， （c）研究统计关系， 产生的共振峰转换的光谱和时间特性 运动性语言障碍患者。该实验计划旨在解决 这些目标包括自然观察肺间质的协变， 上述音量变量和声学/感知测量， 单病例设计方法，以评估患者学习肺部的能力 音量的变化，以及一个范例，其中语速是 故意改变，目的是为了引起变化， 发音过程在实现上述具体目标后， 我们应该更好地理解 神经系统疾病患者的沟通缺陷，因此 更好地了解如何最好地处理赤字。
