随着涉及社交人机交互的应用程序越来越多，能够有效吸引用户的社交响应语音界面发挥着越来越重要的作用。例如，学习伙伴为学生提供与任务相关的反馈和动机支持，以提高学习水平。随着学习伙伴的社交反应能力的提高，学习成果也会提高。本文提出了一种用于实体机器人学习伙伴的社交响应语音界面。我们探索两种社会响应方法。第一种方法将社会反应引入对话中，而第二种方法则通过基于声学韵律夹带的语音适应来增强这些反应。我们评估了社交、语音自适应机器人学习伴侣对社交存在和融洽关系等社会变量的影响，并将其与仅具有社交对话的伴侣和既没有社交对话也没有语音适应的伴侣进行了比较。我们将其影响与性别等个人因素的影响进行了对比。我们发现（1）社交语音自适应语音界面的社交存在感明显高于纯粹的社交对话，（2）女性比男性感觉更融洽，并且在与机器人学习伙伴的互动中更持久。
With a growing number of applications involving social human-robot interactions, there is an increasingly important role for socially responsive speech interfaces that can effectively engage the user. For example, learning companions provide both task-related feedback and motivational support for students with the goal of improving learning. As a learning companion's ability to be socially responsive increases, so do learning outcomes. This paper presents a socially responsive speech interface for an embodied, robotic learning companion. We explore two methods of social responsiveness. The first method introduces social responses into the dialogue, while the second method augments these responses with voice-adaptation based on acoustic-prosodic entrainment. We evaluate the effect of a social, voice-adaptive robotic learning companion on social variables such as social presence and rapport, and we compare this to a companion with only social dialogue and one with neither social dialogue nor voice-adaptions. We contrast the effects against those of individual factors, such as gender. We find (1) that social presence is significantly higher with a social voice-adaptive speech interface than with purely social dialogue, and (2) that females feel significantly more rapport and are significantly more persistent in interactions with a robotic learning companion than males.
