Abstract
Method and apparatus are disclosed for adapting linguistic speech models in automatic speech recognition systems using speech recognition results obtained during operation of such systems, in which, during the adaptation, a list of N-best recognition result alternatives with N>1 for a speech utterance to be recognized is evaluated. To improve such an on-line adaptation of the linguistic speech models, a combination of a plurality of recognition result alternatives of the list is included in the adaptation.
