Information for identifying whether a word should be recognized in the next recognition operation is stored in a recognition dictionary. This information is updated each time the recognized result is obtained in order to update the word for the next recognition, making it possible to prevent an incorrect recognition from being repeated. An indication of whether each word can be entered repeatedly is stored as identification information in the recognition dictionary. When the recognized word is a word which cannot be entered repeatedly, the identification information of the word is updated, thereby reducing the probability of incorrect recognition in the next recognition operation by excluding the word from the next recognition operation. Even when the recognized word is a word which can be entered repeatedly, the word is excluded from the next recognition operation when an instruction is issued from an instruction device. Thus, it is possible to reflect the will of the user in the recognition operation, and to decrease the probability of an incorrect recognition. The incorrect operation performed as a result of the incorrect recognition of the input information is recovered by an easy operation, and the burden on the user is lessened by preventing the repetition of an incorrect recognition operation.
