Method for recognizing speech to avoid over-adaptation during online speaker adaptation |
摘要 |
To avoid an over-adaptation of a current acoustic model (CAM) to certain and frequently occuring words for speech phrases during on-line speaker adaptation of speech recognizers it is suggested to count adaptation numbers (a<SUB>j</SUB>) for each of said speech phrases (SPj) as numbers of times in that a distinct speech phrase (SPj) has been used as a basis for adapting said current acoustic model (CAM) and further to make the strength of adaptation of the current acoustic model (CAM) on the basis of said distinct speech phrase (SPj) dependent on its specific adaptation number (a<SUB>j</SUB>) so as to decrease the influence of frequent speech phrases (SPj) in the received speech flow on the adaptation process.
