PROBLEM TO BE SOLVED: To provide a speech dialogue method and its device with which discrimination is made to discriminate the validity/invalidity of input information at the time of re-opening when the dialogue of a speech dialogue system is interrupted and then, it is re-opened. SOLUTION: The speech dialogue device consists of an interactive history generating device 11 which generates a dialogue history of input information being inputted before the interrupted point of time of the dialogue and which consists of the control program position of the dialogue scenario that is being executed at that point of time and time information at that point of time, and of a dialogue history obtaining device 4 which takes out the dialogue history obtained by the dialogue history generating device 11 and judges whether the time information within the input information is still valid or not while referring to the time information in the input information within the taken out dialogue history to the time information at the point in time of dialogue reopening.
