Abstract
A method and apparatus for carrying out adaptation using input speech data information even at a low reference pattern recognition performance. A reference pattern adaptation deviceincludes a speech recognition section, an adaptation data calculating sectionand a reference pattern adaptation section. The speech recognition sectioncalculates a recognition result teacher label from the input speech data and the reference pattern. The adaptation data calculating sectioncalculates adaptation data composed of a teacher label and speech data. The adaptation data is composed of the input speech data and the recognition result teacher label corrected for adaptation by the recognition error knowledge which is the statistical information of the tendency towards recognition errors of the reference pattern. The reference pattern adaptation sectionadapts the reference pattern using the adaptation data to generate an adaptation pattern.
