Purpose Coordination of communicative behavior supports shared understanding in conversation. The current study brings together analysis of two speech coordination strategies, entrainment and compensation of articulation, in a preliminary investigation into whether strategy organization is shaped by a challenging communicative context—conversing with a person who has a communication disorder. Method As an initial clinical test case, an automated measure of articulatory precision was analyzed in a corpus of spoken dialogue, where a confederate conversed with participants with traumatic brain injury ( n = 28) and participants with no brain injury ( n = 48). Results Overall, the confederate engaged in significant entrainment and high compensation (hyperarticulation) in conversations with participants with traumatic brain injury relative to significant entrainment and low compensation (hypoarticulation) in conversations with participants with no brain injury. Furthermore, the confederate's articulatory precision changed over the course of the conversations. Conclusions Findings suggest that the organization of conversational coordination is sensitive to context, supporting synergistic models of spoken dialogue. While corpus limitations are acknowledged, these initial results point to differences in the way in which speech strategies are realized in challenging communicative contexts, highlighting a viable and important target for investigation with clinical populations. A framework for investigating speech coordination strategies in tandem and ideas for advancing this line of inquiry serve as key contributions of this work.

发音的对话协调对上下文的反应：脑外伤的临床测试案例

目的沟通行为的协调支持对话中的共同理解。目前的研究汇集了对两种言语协调策略（发音的夹带和补偿）的分析，初步调查了策略组织是否是由具有挑战性的沟通环境（与患有沟通障碍的人交谈）形成的。 方法作为最初的临床测试案例，在口语对话语料库中分析了发音精度的自动测量，其中一名同盟者与患有创伤性脑损伤的参与者进行了交谈（n= 28）和没有脑损伤的参与者（n= 48）。 结果总体而言，与没有脑损伤的参与者交谈时，同盟者在与创伤性脑损伤的参与者的对话中进行了显着的夹带和高补偿（过度发音），而相对于在与没有脑损伤的参与者的对话中进行了显着的夹带和低补偿（低发音）。此外，同伙的发音精确度在谈话过程中发生了变化。 结论研究结果表明，对话协调的组织对上下文很敏感，支持口语对话的协同模型。尽管承认语料库的局限性，但这些初步结果表明，在具有挑战性的交流环境中实现言语策略的方式存在差异，突出了临床人群研究的可行且重要的目标。协同研究语音协调策略的框架和推进这一研究方向的想法是这项工作的关键贡献。
