A MULTI-LAYER ARCHITECTURE FOR SEMI-SYNCHRONOUS EVENT-DRIVEN DIALOGUE MANAGEMENT

Abstract

We present a new architecture for spoken dialogue systems that explicitly separates the discrete, abstract representation used in the high-level dialogue manager and the continuous, real-time nature of real world events. We propose to use the concept of conversational floor as a means to synchronize the internal state of the dialogue manager with the real world. To act as the interface between these two layers, we introduce a new component, called the Interaction Manager. The proposed architecture was implemented as a new version of the Olympus framework, which can be used across different domains and modalities. We confirmed the practicality of the approach by porting Let’s Go, an existing deployed dialogue system to the new architecture.
