Dialogue Processing for Voice Interactive Systems

点击翻译按钮获取中文摘要

This research, undertaken in collaboration with Alan W. Biermann of Duke University, is concerned with the problem of how to int- eract with a computer system in natural language by voice. It continues and builds on the results of research carried out by the investigators over the past seven years. Working in the problem domain of electronic equipment repair, they are currently investigating a range of interactive modes from "passive" (the computer merely follows orders and answers questions) to "direct- ive" (it takes charge and questions and instructs the human user). They are also investigating the nature and role of com- ments in a task-oriented dialog and ways of representing and generating appropriate, fully grammatical, natural language spo- ken responses. The motivating goal of the research is to be able to design a machine partner, capable of natural language voice dialogue, and able to assist human beings of varying abilities and experience in an electronic repair task. Progress toward this goal contrib- utes in important ways to knowledge of how to employ automata in roles previously possible only for skilled human beings.
