Carmen in Gina s office. Gina and Carmen interact through spoken dialog. In order to add realism and maximize the expressive effect of this dialog recorded dialog of voice actors is used instead of speech synthesis. A significant amount of variability in the generated dialog is supported by breaking the recordings into meaningful individual phrases and fragments. Additionally variability is achieved by recording multiple variations of the dialog in content and emotional expression . The agents compose their dialog on the fly. The dialog is also annotated with its meaning intent and emotional content. The agents use the annotations to understand each other to decide what to say and more generally to interact. The agents experience the annotations in order so their internal state and appearance can be in flux over the dialog segment. 3. Agent Architecture The agent architecture is depicted in Figure . There are modules for problem solving dialog emotional appraisal and physical focus. The problem solving module is the agent s cognitive layer specifically its goals planning and deliberative reaction to world events. The dialog module models how to use dialog to achieve goals. Emotional appraisal is how the agent emotionally evaluates events . the dialog annotations . Finally physical focus manages the agent s nonverbal behavior. There are several novel pathways in the model worth noting. The agent s own acts feed back as input. Thus it is possible for the agent to say something and then emotionally and cognitively react to the fact that it has said it. Emotional appraisal impacts problem solving dialog and behavior. Finally there are multiple inputs to physical focus from emotional appraisal dialog and problem solving all competing for the agent s physical resources arms legs mouth head etc. .
