A Data-driven Model for Timing Feedback in a Map Task Dialogue System

Raveesh Meena, Gabriel Skantze, Joakim Gustafson

We present a data-driven model for detecting suitable response locations in the user's speech. The model has been trained on human–machine dialogue data and implemented and tested in a spoken dialogue system that can perform the Map Task with users. To our knowledge, this is the first example of a dialogue system that uses automatically extracted syntactic, prosodic and contextual features for online detection of response locations. A subjective evaluation of the dialogue system suggests that interactions with a system using our trained model were perceived significantly better than those with a system using a model that made decisions at random.
