Phonetic processing of speech using Praat

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
