Vowels in Speaker Verification

In the paper the possibility of using a single vowel in peoplespsila identity verification process is described. The usage of sounds which period do not change over the whole duration time, allows applying Fourier series to its analysis. The amplitudes of consecutive harmonics as well as their frequencies are the basis of creating individual featurespsila vector. In order to record sounds of such characteristic, the acquisition process has been performed taking strict measurementpsilas assumption into consideration. The similarity measure of two vowels can be a coefficient which construction is based on the Euclidean distance with contribution of particular components.
