Generation of utterances based on visual context information

A major aspect of spontaneous dialogs is resembled by the collaborative process of communication where participants of a dialog cooperate by the production of utterances. Accordingly, not only independent utterances are produced but an utterance started by one agent may be continued by the other one based on the structural properties provided so far by the initial utterance. For establishing collaboration in dialogs the computer has to cooperate with the user in so far that the instructions of the user are resumed and carried on by the simulation model in that an appropriate continuation is generated by the system.
