Abstract
At least one recognized keyword is presented to a user, and the keyword is corrected appropriately upon receipt of a correction for the presented result. A standby-word dictionary used for recognition of uttered speech is generated according to a result of the correction to recognize the uttered speech. Therefore, even if recognized keywords contain an error, the error can be corrected and uttered speech can be accurately recognized.
