PROBLEM TO BE SOLVED: To solve the problem that a conventional voice interactive devices where a keyword mutual relation extending over plural utterance is not considered, a user is recognized at every utterance for improving a interactive success rate, multiple recognition communication are executed and the convenience of the user and the naturalness of communication are damaged. SOLUTION: The interactive device is provided with a interactive procedure storage part storing the vocabulary of a recognition object in respective interactive states, a system response, a system response assumption response and a transition destination interactive state corresponding to the response, a voice recognition part recognizing voice with the vocabulary of the recognition object in the respective interactive states of the interactive procedure storage part and outputting plural results, a transition destination interactive state deciding operation deciding part deciding a transition destination interactive state according to the recognition result of the voice recognition part and the content of the interactive procedure storage part, deciding one state when the hypothesis of the transition destination interactive state satisfies a prescribed condition, holding decision when it does not satisfy the prescribed condition and outputting the hypothesis of the shift destination interactive state, and an interactive operation execution part outputting the system response recognizing the recognition result of the hypothesis of the transition destination interactive state when hypothesis is decided and outputting the system response of the hypothesis of the transition destination interactive state when decision is held. |
