在人与人之间的互动中，人们有时能够敏感地捕捉到对方的内在状态，并做出反应，因为它在交流过程中时刻发生变化。为了了解这种能力是否值得用于计算机人机界面，我们构建了一个半自动辅导型口语对话系统。该系统从用户话语的韵律和上下文中推断出有关用户的“短暂情感”的信息，如自信、困惑、快乐和依赖。它利用这一信息在每一时刻选择最适当的确认形式。在这样做的过程中，系统遵循了一些实时交互的基本社会惯例。用户对具有此功能的系统的评价高于没有此功能的版本。
In human-to-human interaction, people sometimes are able to pick up and respond sensitively to the other's internal state as it shifts moment by moment over the course of an exchange. To find out whether such an ability is worthwhile for computer human interfaces, we built a semi-automated tutoring-type spoken dialog system. The system inferred information about the user's \scare{ephemeral emotions}, such as confidence, confusion, pleasure, and dependency, from the prosody of his utterances and the context. It used this information to select the most appropriate acknowledgement form at each moment. In doing so the system was following some of the basic social conventions for real-time interaction. Users rated the system with this ability more highly than a version without.
