Abstract
Ovaj završni rad bavi se proučavanjem metoda i tehnika digitalne obrade govora te prikaza govornih signala. Opisane su Z-transformacije i Fourierove transformacije kao tehnike analize govornih signala kojima se određuju određene karakteristike tog signala, te njihov grafički prikaz u vidu spektrogramske analize glasovnog signala. Obrađene su jednostavnije metode digitalnog enkodiranja poput PCM-a, DPCM-a i ADPCM-a. Prikazan je i razvoj LPC-a i CELP-a kao tehnologija za rekreiranje i kompresiju govornog signala. Za sam kraj obrađene su moderne tehnike digitalne obrade govora poput VoIP-a, HMM-a i ANN-ova te njihova uloga u svakidašnjem životu ljudi.
Abstract (english)
This thesis studies the methods and techniques of digital speech signal processing and representation of speech signals. Z-transformations and Fourier's transformations are described as techniques for analysis of speech signals that determine specific characteristics of those signals, and allow for a graphical representation in form of a spectrogram. Then it elaboretes elementary methods of digital speech encoding such as PCM, DPCM and ADPCM. Furthermore, LPC and CELP are represented as techonologies for recreating and compressing of speech signals. Lastly, VoIP, HMM and ANNs are depicted as modern techniques for digital speech processing and their role in everyday human lives is described.
