26. A speaker adaptation method comprising:
-
extracting speech recognition data from a database, wherein the speech recognition data comprises one of a first type of data and a second type of data, wherein the first type of data comprises input speech data and data generated by correctly recognizing the input speech data, and the second type of data comprises input speech data and data generated when an error in text data generated by incorrectly recognizing the input speech data is corrected; selecting a first speaker adaptation method when the extracted speech recognition data comprises the first type of data, and selecting a second speaker adaptation method, different from the first speaker adaptation method, when the extracted speech recognition data comprises the second type of data; and modifying a sound model using the selected speaker adaptation method.
