<p>The invention relates to a digital method for authenticating a person by comparing a current voice profile to a previously stored initial voice profile, wherein the person speaks at least one speech sample in order to determine the respective voice profile, the spoken speech sample is fed to a voice profile computing unit, and based on a predefined voice profile algorithm the voice profile is computed. For the, or every, speech sample, a phoneme structure and a sequence of weighting factors associated with the phonemes, and/or a phonematic evaluation coefficient are determined by means of voice recognition with subsequent phonematic analysis, and the weighting factors and/or the evaluation coefficient are used to determine a confidence value of the voice profile and/or to control to whether the respectively spoken speech sample or parts thereof are fed to the voice profile computing unit.</p> |
