Abstract Considerable work has been done regarding usability evaluation of task-oriented unimodal spoken language dialogue systems (SLDSs). However, there are still important gaps in our knowledge even in this area. If we move to multimodal task-oriented SLDSs, there are more challenges ahead primarily due to the combination of different modalities. For non-task-oriented conversational SLDSs, a major challenge is the new evaluation issues brought up by the nature of conversation. This paper presents a state-of-the-art in usability evaluation of these new types of SLDSs and conclusions based on the experience we have today.
