在本文中，作者提出了一个任务无关的控制方法的口语对话。这是在基于文本的对话系统中使用的框架驱动对话控制方法的扩展，该方法使用数据库和框架来使用特定于任务的知识。该框架由一组可以在特定任务中处理的相关主题、优先级排序以及每个主题完成时系统的行为组成。当在主题之间存在层次关系时，这被描述为帧之间的层次关系。对话历史由主题框架使用可以提供动态链接的树结构（这被称为动态主题树）来表示。系统主动和用户主动对话可以通过使用两种类型的方法搜索动态主题树来实现。作者创建了一个口语对话系统的四个典型的任务，并进行口语对话实验，以评估系统。结果表明，所有受试者都能够完成任务。这表明，作者的方法是有效的，作为一种方法来创建一个实用的任务无关的口语对话系统。© 2004 Wiley Periodicals，Inc.

In this paper the authors propose a task‐independent control method for spoken dialogs. This is an expansion of the frame‐driven dialog control method used in text‐based dialog systems, which employs knowledge specific for a task using a database and frames. The frame consists of a set of related topics that can be treated in specific tasks, the priority ranking, and the behavior of the system when each topic is completed. When there is a hierarchical relationship among topics, this is described as a hierarchical relationship among frames. The dialog history is represented by the topic frame using a tree structure that can provide dynamic links (this is called a dynamic topic tree). System‐initiative and user‐initiative dialog can be accomplished by searching the dynamic topic tree using two types of approaches. The authors created a spoken dialog system for four typical tasks and performed spoken dialog experiments in order to evaluate the system. The results showed that all subjects were able to complete the tasks. This demonstrates that the authors' method is valid as a way to create a practical task‐independent spoken dialog system. © 2004 Wiley Periodicals, Inc.
