言语趋同是说话者变得与他们正在听或说话的人更相似的趋势，无论那个人是对话伙伴还是仅仅是听到重复单词的声音。本研究采用不同难度的任务对合作完成同一任务的二人组进行言语聚合实验，以阐明言语聚合机制的本质。Dyad成员必须建造相同的乐高（R）建筑，而不能看到对方的建筑，每个成员都有一半的指令来完成建筑。创建了三个级别的任务难度，每个级别有五对（共30名参与者）。任务难度也用完成时间和错误率来衡量。听众谁听到的话语对从每个二分体判断收敛发生在容易的条件下，并在较小程度上在中等条件下，但不是在硬条件。振幅包络声学相似性分析相同的话语对表明，收敛发生在较短的完成时间和较低的错误率的二进制。总之，这些结果表明，虽然言语收敛是一种高度可变的行为，但它可能更多地发生在低认知负荷的环境中。目前的自动和社会驱动的收敛模型，这些结果的相关性进行了讨论。
Speech convergence is the tendency of talkers to become more similar to someone they are listening or talking to, whether that person is a conversational partner or merely a voice heard repeating words. To elucidate the nature of the mechanisms underlying convergence, this study uses different levels of task difficulty on speech convergence within dyads collaborating on a task. Dyad members had to build identical LEGO (R) constructions without being able to see each other's construction, and with each member having half of the instructions required to complete the construction. Three levels of task difficulty were created, with five dyads at each level (30 participants total). Task difficulty was also measured using completion time and error rate. Listeners who heard pairs of utterances from each dyad judged convergence to be occurring in the Easy condition and to a lesser extent in the Medium condition, but not in the Hard condition. Amplitude envelope acoustic similarity analyses of the same utterance pairs showed that convergence occurred in dyads with shorter completion times and lower error rates. Together, these results suggest that while speech convergence is a highly variable behavior, it may occur more in contexts of low cognitive load. The relevance of these results for the current automatic and socially-driven models of convergence is discussed.
