The communication phenomenon known as conversational entrainment occurs when dialogue partners align or adapt their behavior to one another while conversing. Associated with rapport, trust, and communicative efficiency, entrainment appears to facilitate conversational success. In this work, we explore how conversational partners entrain or align on articulatory precision or the clarity with which speakers articulate their spoken productions. Articulatory precision also has implications for conversational success as precise articulation can enhance speech understanding and intelligibility. However, in conversational speech, speakers tend to reduce their articulatory precision, preferring low-cost, imprecise speech. Speakers may adapt their articulation and become more precise depending on feedback from their listeners. Given the potential of entrainment, we are interested in how conversational partners adapt or entrain their articulatory precision to one another. We explore this phenomenon in 57 task-based dialogues. Controlling for the influence of speaking rate, we find that speakers entrain on articulatory precision, with significant alignment on articulation of consonants. We discuss the potential applications that speaker alignment on precision might have for modeling conversation and implementing strategies for enhancing communicative success in human-human and human-computer interactions.
当对话伙伴在交谈时彼此调整或使自己的行为与对方一致时，就会出现被称为对话趋同的交流现象。趋同与融洽关系、信任和交流效率相关，似乎有助于对话成功。在这项研究中，我们探讨了对话伙伴如何在发音精度或说话者清晰表达其言语产出的清晰度方面实现趋同或保持一致。发音精度对对话成功也有影响，因为精确发音可以提高言语理解度和清晰度。然而，在对话言语中，说话者往往会降低发音精度，更喜欢低成本、不精确的言语。说话者可能会根据听众的反馈调整发音，变得更加精确。鉴于趋同的潜力，我们感兴趣的是对话伙伴如何相互适应或在发音精度上实现趋同。我们在57个基于任务的对话中探究了这一现象。在控制了语速的影响后，我们发现说话者在发音精度上实现了趋同，在辅音发音上有显著的一致性。我们讨论了说话者在精度上的趋同可能对对话建模以及在人机交互和人际交互中实施提高交流成功率的策略所具有的潜在应用。
