SOLUTION: In a continuous speech sentence input device 10, a speech command history management part 18 stores a use frequency of each speech command used when a user has inputted sentences in speech. A dictionary management part 19 for speech command monitors the contents stored in the speech command history management part 18, and when all the speech commands have been used by a predetermined times, the management part checks whether each speech command counts the predetermined least use frequency, and if any speech command does not count the least use frequency, it is eliminated from a speech command dictionary 14. |
