Claim 8:
9. The method of claim 6, wherein the difference of magnitudes of the plurality of electrical signals comprises a plurality of differences of magnitudes of the plurality of electrical signals, and the recognizing the speaker further comprises:
assigning a weight to a model corresponding to the determined vowel in an authentication template;
generating the bitmap of the band gradient based on a first difference of magnitudes of the plurality of electrical signals, which is different from a second difference of magnitudes of the plurality of electrical signals used to determine the vowel;
generating a characteristic value based on the bitmap of the band gradient; and
recognizing whether the speaker is a registered speaker based on comparison between the characteristic value and the authentication template, in which the model corresponding to the determined vowel is assigned the weight.
