We present an integrated authoring tool for rapid pro-totyping of dialogue systems for virtual humans taking part in tactical questioning simulations. The tool helps domain experts, who may have little or no knowledge of linguistics or computer science, to build virtual characters that can play the role of the interviewee. Working in a top-down fashion, the(More)
We extend a virtual human architecture that has been used to build tactical questioning characters with a parameterizable personality model, allowing characters to be designed with different personalities, allowing a richer set of possible user interactions in a training environment. Two experiments were carried out to evaluate the framework. In the first,(More)
