ChatWoz: Chatting through a Wizard of Oz

Several cases of autistic children successfully interacting with virtual assistants such as Siri or Cortana have been recently reported. In this demo we describe ChatWoz, an application that can be used as a Wizard of Oz, to collect real data for dialogue systems, but also to allow children to interact with their caregivers through it, as it is based on a virtual agent. ChatWoz is composed of an interface controlled by the caregiver, which establishes what the agent will utter, in a synthesised voice. Several elements of the interface can be controlled, such as the agent's face emotions. In this paper we focus on the scenario of child-caregiver interaction and detail the features implemented in order to couple with it.
