摘要
A speech recognition system includes a feature extraction component that receives a speech signal and extracts feature vectors from the speech signal. Also included, is a decoder having a speech acoustic model, a feature modification component, and a comparison component. The feature modification component changes the feature vectors, using adaptation data and prior data, to more closely match. the speech acoustic model. The comparison component utilizes the modified feature vectors and the speech acoustic model to recognize the speech signal.
