For the sake of data reduction in automatic speech recognition often vector quantization based on a previously generated code book is performed. ln the approach described here the necessary code book is set up by means of a selforganizing dustering technique. lt takes the shape of a two-dimensional array of feature vectors. Phonetically similar vectors are(More)
This paper presents a new approach to combine several biometrics in a multimodal device. The proposed approach does not use typical fusion strategies but is based on the multi-dimensional cost probability densities of the originals and forgers, which can be measured or calculated from the intrinsic cost or score distribution of the single biometrics, and(More)
