Abstract

This Bachelor's Thesis deals with the techniques of the speech recognition and key words spotting using hidden Markov models. The first part of my thesis contains a description of the techniques of parameterization of the signals, models training and algorithms of speech recognition. In the second part, the detection of key words with several models trained on speech signals recorded in different distances is investigated and the results of the tests are evaluated

Topics: speech recognition; skryté Markovovy modely; Hidden Markov Model (HMM); Keyword spotting (KWS); rozpoznávání řeči; HMM training; trénování skrytých Markovových modelů; The Hidden Markov Model Toolkit (HTK); detekce klíčových slov
