An apparatus and method for recognizing paraphrases of uttered phrases, such as place names. At least one keyword contained in a speech utterance is recognized. Then, the keyword(s) contained in the speech utterance are re-recognized using a phrase including the keyword(s). Based on both recognition results, it is determined whether a paraphrase could have been uttered. If a paraphrase could have been uttered, a phrase corresponding to the paraphrase is determined as a result of speech recognition of the speech utterance.

Speech recognition apparatus and method

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.
