The invention relates to a method for identifying people, whereby a person is identified by comparing an electric signal derived from a sound produced by the person with a stored signal of the above kind. The invention is characterized in that the signals to be compared are derived from the subphonemic range of sound production. The signal especially refers to a quasiperiod of a vowel or a semivowel.
