我们提供了一个动态模型的语音规划，提供了一个正式的实例，如何在网上处理的语音生产和感知系统的相互作用。该模型的基础上开发的实验任务，需要同时使用这两个系统，所谓的响应分心任务，扬声器听到分心音节，而他们正准备产生所需的反应的证据。该模型正式说明了正在进行的应对计划如何受到感知的影响，并解释了以往研究报告的一系列结果。它通过显式地处理表示中参数值的设置来实现。该模型的关键单元是动态场，即与每个代表性参数相关的值范围内的激活分布。参数值的设置通过在整个场上实现激活的稳定分布来进行，在甚至在上述实验中的响应线索被移除之后它仍然存在的意义上是稳定的。这一点和其他属性的表示已被视为公理在以前的工作中所提出的模型的动力学推导。
We offer a dynamical model of phonological planning that provides a formal instantiation of how the speech production and perception systems interact during online processing. The model is developed on the basis of evidence from an experimental task that requires concurrent use of both systems, the so-called response–distractor task in which speakers hear distractor syllables while they are preparing to produce required responses. The model formalizes how ongoing response planning is affected by perception and accounts for a range of results reported across previous studies. It does so by explicitly addressing the setting of parameter values in representations. The key unit of the model is that of the dynamic field, a distribution of activation over the range of values associated with each representational parameter. The setting of parameter values takes place by the attainment of a stable distribution of activation over the entire field, stable in the sense that it persists even after the response cue in the above experiments has been removed. This and other properties of representations that have been taken as axiomatic in previous work are derived by the dynamics of the proposed model.
