Claim 16:
17. The method according to claim 14, comprising performing a score calibration σ(χ) of the user or speaker authentication; wherein χ represents a score of the user or speaker authentication; and wherein the closer to 1 is σ(χ), the more successful the user or speaker authentication is determined, and the closer to 0 is σ(χ), the less successful the user or speaker authentication is determined; and wherein
when the score calibration σ(χ) lies between the predefined calibration threshold and the predefined heuristic factory, the remembering factor λ(σ(χ),ψ, γ) is equal to, (
        
          γ
