According to the interpersonal synergy model of spoken dialogue, interlocutors modify their communicative behaviors to meet the contextual demands of a given conversation. Although a growing body of research supports this postulation for linguistic behaviors (e.g., semantics, syntax), little is understood about how this model applies to speech behaviors (e.g., speech rate, pitch). The purpose of this study is to test the hypothesis that interlocutors adjust their speech behaviors across different conversational tasks with different conversational goals.
In this study, 28 participants each engaged in two different types of conversations (i.e., relational and informational) with two partners (i.e., Partner 1 and Partner 2), yielding a total of 112 conversations. We compared six acoustic measures of participant speech behavior across conversational task and partner.
Linear mixed-effects models demonstrated significant differences between speech feature measures in informational and relational conversations. Furthermore, these findings were generally robust across conversations with different partners.
Results suggest that contextual demands influence speech behaviors. These findings provide empirical support for the interpersonal synergy model and highlight important considerations for assessing speech behaviors in individuals with communication disorders.
根据口语对话的人际协同模型，对话者会调整自己的交际行为，以适应特定对话的语境需求。尽管越来越多的研究支持这一假设，即该模型适用于语言行为（如语义、句法），但对于该模型如何适用于言语行为（如语速、音高等），人们知之甚少。本研究旨在检验以下假设：对话者会根据不同的会话目标调整不同会话任务中的言语行为。
在这项研究中，28 名参与者分别与两位搭档（即搭档 1 和搭档 2）进行了两种不同类型的对话（即关系型对话和信息型对话），共产生了 112 次对话。我们比较了参与者在会话任务和搭档方面的六种言语行为的声学测量指标。
线性混合效应模型表明，信息型对话和关系型对话中的言语特征测量值存在显著差异。此外，这些发现通常在与不同搭档的对话中具有稳健性。
结果表明语境需求会影响言语行为。这些发现为人际协同模型提供了实证支持，并强调了在评估言语障碍个体的言语行为时需要考虑的重要因素。
