Phonetic processing of speech using Praat
 Kráčala, Martin ; Staněk, Miroslav (referee) ; Sigmund, Milan (advisor)
The goal of this bachelor thesis is to create a Czech manual for beginners with software Praat. Praat is a software package designed for speech processing. It can be used for speech analysis and synthesis. In this work is described Praat user interface, operations with files in the program, sound recording, editing and analysis of these sounds. Manual is supplemented with examples of solved phonetic problems. The second goal of this thesis is to create a script to extract vowels and some consonants from voice records. The thesis contains description of chosen principles of recognition of vowels based on formants and intensity contour and the principle of recognition of consonants based on the ratios of energy in predetermined frequency bands. The success rate of the script is thoroughly examined and various optimization methods are discussed.

 Opletalová, Kateřina ; Duběda, Tomáš (advisor) ; Tylečková, Lea (referee)
(in English): This thesis focuses on phonetic analysis of political discourse. Four most successful candidates from French presidential elections 2012 were chosen. The aim is to evaluate whether phonetic part of the speech is intentionally modified to satisfy target audience. Results are rather conclusive - there are essential differences among candidates. Contrary to expectations the highest style was found in speech of Marine Le Pen. Other speakers basically used standard style which varied in specific components. Several explanations for all these differencies were presented.
