Zusammenfassung:	An interactive dialogue apparatus generates prompts and receives responses which it processes and stores response data. Progress of the dialogue is controlled using a state model which is parsed, comparing transition conditions with the stored response data, stopping at a state for which no edge condition is satisfied. Each time a fresh response is received, the mod el is reparsed from the start. Prompts are generated by reference to a state history, being selected by finding the longest match between the history and state sequences associated with stored prompts. Prompts are compared so that the dialogue may be terminated in the event of repetition.
