摘要： PROBLEM TO BE SOLVED: To efficiently conduct voice conversation between a user and a system by eliminating the system output which is for confirmation only and providing the recognition results including a neat guidance sentence. SOLUTION: A conversation control means 5 requests the guidance contents which urge the next action to a task control means 10. The response to the request is a question for a name. Then, the means 5 asks for a latest keyword to a keyword holding means and obtains the 'Material Section' which has been just POPed. Then, the means 5 transmits the next guidance contents and the latest keyword to an response generating means 7 and instructs it to generate a response sentence. Then, the means 7 generates a question sentence, such as 'What is your name in the Material Section?' and transmits the sentence to a voice output means 5. Then, the means 5 sends the recognition vocabulary to a recognition vocabulary supplementing means 3 in order to confirm the name.
