1. A device for the computer-aided ascertainment of feature vectors from a signal for voice recognition, comprising: a unit for forming intermediate feature vectors from the signal, at least some of the components of the intermediate feature vectors having a power spectrum from part of the digitized signal; a high-pass filter, which is coupled to the unit for forming intermediate feature vectors, for high-pass filtering the intermediate feature vectors; a weighting unit, which is coupled to the unit for forming intermediate feature vectors, for multiplying the intermediate feature vectors by a weighting factor; and a signal addition unit which is set up to add a respective prescribed addition feature vector at least to some of the high-pass-filtered intermediate feature vectors, the addition feature vectors used being the respective intermediate feature vectors multiplied by the weighting factor.
