  In order to take up the challenge of realising user-adaptive system
behaviour, we present an extension for the existing OwlSpeak Dialogue Manager
which enables the handling of dynamically created dialogue actions. This leads
to an increase in flexibility which can be used for adaptation tasks. After the
implementation of the modifications and the integration of the Dialogue Manager
into a full Spoken Dialogue System, an evaluation of the system has been
carried out. The results indicate that the participants were able to conduct
meaningful dialogues and that the system performs satisfactorily, showing that
the implementation of the Dialogue Manager was successful.
