Abstract

U ovom radu opisan je postupak identifikacije govornika pomoću formanata govornog signala i modeliranjem Gaussovim mješavinama. Postupak je opisan za 4 govornika na način da su snimljeni izgovori samoglasnika te su iz tih zvučnih zapisa u MATLAB-u izvučene karakteristike formanata. Izgrađeni su modeli s Gaussovim mješavinama za svakog govornika sa ciljem da program identificira govornika iz snimke koja nije korištena za treniranje modela.

Abstract (english)

This paper explains the speaker identification system using formants of the speech signal and Gauss mixture models. The procedure is based on audio recordings in which speakers pronounce 6 vowels, which are then used to extract formant featurs using MATLAB with a total of 4 known speakers. Gauss mixture models are built for each of the speakers with a goal to identify the speaker from the audio recording which was not used in training of the models.
