Interaction and participation are in the kernel of the new medium of games. The ultimate goal is the “participatory game”, where interactive games and storytelling are merged. One of the most complex forms of this type of game is the narrated ones. This paper presents an architecture that incorporates a virtual narrator, capable of emotional expressions synchronized with speech, to an interactive storytelling system, in order to create a new form of participatory game, in which the player is co-author of the plot.
