Little is known about the cognitive capacities underlying real-time accommodation in spoken language and how they may allow conversing speakers to adapt their speech production behaviors. This study first presents a simple attunement model that incorporates hypothesized capacities, with a focus on individual variability as one of those capacities. The model makes explicit predictions about observable convergence behaviors in interacting speakers, including that: i) the intrinsically more variable speaker of the two will be the one who converges to their partner, ii) this flexible speaker with higher baseline variability will exhibit a substantial decrease in variability and iii) a greater change in the variability between speaking solo and interacting with their partner. These predictions are supported by the results of the modeling simulations. To further test the model's predictions, we analyzed a behavioral dataset including acoustic and articulatory data from three pairs of interacting speakers participating in a maze navigation task as well as a like solo speech task. The amount of variability in the speech parameters of each dyad member was quantified using coefficient of variation. The experimental results parallel the simulation results, and taken together, this work indicates that structured variability is an illuminating index of individual speaker adaptability and convergence behavior.

谁会聚?差异显示单个说话者的适应性

关于实时适应口头语言的认知能力及其如何使交谈的说话者适应其言语产生行为的知识知之甚少。这项研究首先提出了一个简单的调和模型,该模型结合了假设的能力,并着重于个人可变性作为这些能力之一。该模型对交互说话者中可观察到的会聚行为做出了明确的预测,包括:i)内在变化较大的说话者将是与其伴侣会合的说话者; ii)具有较高基线可变性的灵活说话者将表现出明显的下降iii)独奏和与伴侣互动之间的变异性发生较大变化。这些预测得到建模仿真结果的支持。为了进一步测试模型的预测,我们分析了一个行为数据集,包括来自参与迷宫导航任务以及类似语音演讲任务的三对交互说话者的声学和发音数据。使用变异系数来量化每个二元组成员的语音参数中的变异量。实验结果与模拟结果平行,并且一起进行,这项工作表明结构性可变性是单个说话人适应性和收敛行为的照明指标。使用变异系数来量化每个二元组成员的语音参数中的变异量。实验结果与模拟结果平行,并且一起进行,这项工作表明结构性可变性是单个说话人适应性和收敛行为的照明指标。使用变异系数来量化每个二元组成员的语音参数中的变异量。实验结果与模拟结果平行,并且一起进行,这项工作表明结构性可变性是单个说话人适应性和收敛行为的照明指标。
