Abstract
Method and arrangement for a speech recognition system using channel bank information to represent speech. The method considers background noise included with the speech. The method includes determining three energy levels for each channel, the first representative of background noise energy (20), the second representative of the input frame energy (16) and the third representative of the word template frame energy (18). Values representing energy level differentials are assigned at each channel. If the second energy level is less than the first energy level, then a predetermined constant value is assigned at that particular channel. These values are combined to generate a distance measure depicting the similarity between the two frames.
