Analýza kepstra řečových vzorků

Abstract

This bachelor’s thesis is thematically focused on extraction of fundamental frequency of the human voice from the sound record. The process of analysis and subsequent evaluation is carried out by three methods, namely cepstral analysis, Mel-frequency cepstral coefficients analysis and autocorrelation function. Each method use different procedures for extraction of the fundamental frequency. The objective is evaluation of these differences and determine the suitability of each method for a certain type of speech sample.
