While the notion of a cooperative response has been the focus of considerable research in natural lan- guage dialogue systems, there has been little empir- ical work demonstrating how such responses lead to more efficient, natural, or successful dialogues. This paper presents an experimental evaluation of two alternative response strategies in TOOT, a spo- ken dialogue agent that allows users to access train schedules stored on the web via a telephone conver- sation. We compare the performance of two ver- sions of TOOT (literal and cooperative), by hav- ing users carry out a set of tasks with each ver- sion. By using hypothesis testing methods, we show that a combination of response strategy, application task, and task/strategy interactions account for var- ious types of pe...
