随着时间的推移，经常在一起的人（例如室友）的声音开始变得相似。即使在简短的对话过程中，对话者之间在声音上也常常变得更加相似。这种被称为语音对齐的现象在成人互动中已得到充分研究，但人们对代际、成人-儿童二人组中的对齐模式知之甚少。在当前的研究中，我们调查了母亲和孩子在图片命名任务中的一致性，并使用感知相似性任务和声学测量进行评估。实验 1 和 2 检查了 2.5 岁和 4 岁儿童及其母亲的一致性，包括当母亲跟随他们的孩子（实验 1）和当孩子跟随他们的母亲（实验 2）时。实验 3 和 4 研究了单独记录时母亲和孩子之间的长期相似性。结果显示，孩子和母亲在跟踪任务中彼此保持一致，无论谁跟踪谁，虽然没有证据表明年幼的孩子会长期保持一致，但有证据表明 8 岁的孩子和他们的母亲会长期保持一致，但仅限于男孩。
Over time, people who spend a lot of time together (e.g., roommates) begin sounding alike. Even over the course of short conversations, interlocutors often become more acoustically similar to one another. This phenomenon – known as phonetic alignment – has been well studied in adult interactions, but much less is known about alignment patterns in intergenerational, adult-child dyads. In the current study, we investigated alignment between mothers and their children in a picture-naming task, as assessed using a perceptual similarity task and acoustic measures. Experiments 1 and 2 examined alignment in 2.5- and 4-year-old children and their mothers, both when mothers shadowed their children (Experiment 1), and when children shadowed their mothers (Experiment 2). Experiments 3 and 4 investigated long-term similarity between mothers and children when they were recorded separately. Results show that children and mothers aligned to one another in the shadowing task, regardless of who shadowed whom, and while there was no evidence for long-term alignment in younger children, therewassome evidence of long-term alignment with 8-year-old children and their moms, but only for male children.
