Autism Spectrum Disorder is a neurodevelopmental condition that can affect autonomy and independence. Our research explores the integration of Cross-Reality and Conversational Agents for Autistic persons to improve ability and confidence in everyday life situations. We combine two technologies of the Virtual-Real continuum. User experiences unfold from the simulation of tasks in VR to the execution of similar tasks supported by AR in the real world. A speech-based Conversational Agent is integrated with both VR and AR. It provides contextualized help, promotes generalization, and stimulates users to apply what they learned in the virtual space. The paper presents the approach and describes an empirical study involving 17 young Autistic persons.
