Abstract
Tema ovog rada dijeli se u dvije cjeline: forenzička audio analiza i prepoznavanje govornika. Na početku rada opisan je razvoj audio medija od fonografa pa sve do SSD diskova. U forenzičkoj audio analizi proučavaju se sva područja forenzičke audio obrade. Proces prepoznavanja govornika vrši se preko određenih atributa glasa. Iz teoretskih proučavanja prirode glasa i promjena atributa razvijeno je nekoliko algoritama i metoda prepoznavanja govora i govornika. Proučavanjem formanta i njihovog podudaranja analizirane su snimke govornika. Uspoređivane su snimke istog govornika, ali drugačijeg tempa, tonaliteta, naglaska govora te računalno dodanim bijelim šumom.
Abstract (english)
This thesis is divided into two sections: forensic audio analysis and speaker recognition. Firstly the development of audio media is described, from the phonograph through SSD disks. The forensic audio analysis studied all areas of forensic audio processing. Speaker recognition is performed using certain voice attributes. Using theoretical studies of the nature of voice and attributes changes, several voice and speaker recognition algorithms and methods have been developed. By analyzing the formants and their correspondence, speakers audio recordings have been studied. Same speaker recordings were compared, but with different speech pace, mode, accent and with computer-added white noise.
