Creation and processing of signal database
Glett, Jiří ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
The work become acquainted with history and rise databases globally. Construes philosophy structuralization, sorting and purpose using. Work further deal with concrete databases softwares intended directly to processing audio signals. Further treat of programmes that the make possible generation personal database structures. Work deal about SUSAS database and analysing its content. It is created self database of music signals, which includes several musical groups always similar in certain aspect. Speech database contains records from the SUSAS database and records from television programs, reality-shows, sports broadcasts, reports and documents, when speakers are subjected to stress and emotions. The work is a database program that can effectively classify all records and processes. The database can be freely extended. The resulting program was realized into Czech and English version.

Program to support correct pronunciation of foreign languages
Malucha, Jan ; Kohl,, Ing, Zdeněk (referee) ; Sigmund, Milan (advisor)
The aim of the diploma thesis is the development of an autonomous program for checking and evaluating the pronunciation of a foreign language. Theoretical part includes a treatise on the history and importance of computer-assisted language teaching; it also contains a brief introduction to phonetics, phonology and pronunciation issues, as well as an introduction to speech signal processing with a focus on computational methods for pronunciation analysis. In the practical part, a search of currently widespread and available tools for pronunciation control was processed and a number of algorithms usable for its analysis were programmed. Some of the algorithms have been enclosed in a graphical user interface as a basic prototype of a functional program to support pronunciation. The achieved results and the direction of further development are discussed in the conclusion.

Automatic Harmony Generation
Bobčík, Martin ; Drahošová, Michaela (referee) ; Vašíček, Zdeněk (advisor)
Goal of this master thesis is to study harmonization based on knowledge of given melody and to design a system which will meaningfully automate this activity. In the work there is covered basics of music theory needed for this topic and previous other approaches to this problematic. There is also covered machine learning, neural networks and recurrent neural networks. In the end, there is outlined design of the system, how to make it work and how to use it. Four experiments were executed with the system. Harmonization of the short melodies were unpleasant. Harmonization of longer melodies were overall more successful though. A possible cause might be relatively small used neural network of the system.

Computer-Generated Music
Chmelka, Jakub ; Polok, Lukáš (referee) ; Fapšo, Michal (advisor)
This bachelor´s thesis deals with the problem of music composition by means of computers. The system uses artificial neural networks which learn the regularities of the chosen music genre from the recordings in MIDI format. In addition to the melody, this work places great emphasis on rhythm of newly created compositions. Besides the problem of neural networks, this work deals with the appropriate representation of input data and re-conversion into MIDI format. The system is implemented as a set of scripts mainly in the mathematical software Matlab.

Computer-Generated Music
Lanc, Jakub ; Štancl, Vít (referee) ; Fapšo, Michal (advisor)
Main topic of the thesis is musical composition by means of computer, specifically usage of neural networks for melody generation. Contemporary artificial music composition approaches are briefly mapped, and some types of neural networks used are presented. Implementation of Matlab scripts, allowing melody generation is presented, and the process is illustrated on a few examples.

Music Creation Using Cellular Automata
Novotný, Pavel ; Martinek, David (referee) ; Peringer, Petr (advisor)
In this thesis the cellular automata are used for algorithmic music composition. It contains a general overview of the algorithmic composition method and cellular automata. The crucial part of the thesis describes the concept and implementation of the program with a graphical user interface which uses two simple methods for conversion cellular automata's states into music. The final program was tested on several cellular automata and the sound outputs of both methods were compared with each other. The program is useful especially for the creation of short melodies.

Aristoxenus of Tarentum - a study on the work Elementa Harmonica
Langhammerová, Gabriela ; Hladký, Vojtěch (advisor) ; Šíma, Antonín (referee) ; Švantner, Martin (referee)
The thesis deals with an Ancient Greek work Elementa Harmonica (Harmonic Elements) written by Aristoxenus of Tarentum and to the same extent with the contexts of the creation of this work. Elementa is primarily a musical-theoretical work, focused mainly on specific parts of which music, and more specifically, melody, consist. There is a huge and thorough description of particular elements including those who tried to deal with the same matter before Aristoxenus himself. Therefore, Elementa are amongst other a very valuable source of collected knowledge concerning both musical theory, methodology and musical practice provided by Aristoxenus' predecessors. However, Elementa have also an interesting methodological approach, combining mathematical (which means basically Pythagorean) and peripathetical (predominantly Aristotelian) attitudes in a unique synthesis leading to an establishment of a brand new position of musical-theoretical research. This thesis shall provide an analysis of the main constituting branches and its further implications. Key words: Aristoxenus of Tarentum, ancient music theory, Elementa Harmonica, methodology of science, history of science, Pythagorean tradition, peripatos, melody, elements
