On the Complexity in Task-oriented Spoken Dialogue Systems
Stefan Ultes, Wolfgang Maier · 2020
The recent rise of personal voice-assistants shows that research in dialogue systems has gone great lengths from its beginnings many decades ago. We argue that recent research on dialogue complexity has concentrated on already known problems and has remained rather static. We present an overview of past work and argue that increasing dialogue complexity should move again to the centre of interest of new research endeavours.
