Kepstrální analýza a liftrování lidské řeči

Abstract

The aim of this thesis is the study of cepstral analysis and liftering of human speech. For this purpose I have implemented algorithms and functions that are needed for the calculation and analysis of the spectrum and cepstrum, especially variants of the FFT algorithm, which is the basis for both analysis. In this study, I compare the efficiency of FFT variants and the best of them I use to process audio signals.
