Multimedia signal processing
Staněk, Miroslav ; Pospíšil, Radek (referee) ; Sigmund, Milan (advisor)
The aim of this thesis is creation the appropriate multimedia support for signals and system with continuous time. The understanding of this issue is very important, because the obligatory subject Signals and systems, exactly BSIS, is taught at the EST bachelor degree. The understanding is also necessary prerequisite to successful understanding next topics in other related subjects. The next part of this thesis is focused on one dimension discrete signals. Concretely, the aim of this part is a realization of software system. Designed system has some basic operations (the signal energy, the number of signal zero crossing etc.) with sound files and also some advance functions e.g. vowel seeking and separating in fluent speech. The system is divided into two main parts. The first one analyzes sound files, creates the new sound file with wanted vowel and matrices with important parameters for other processing. The second program computes with given data, which statistically evaluates in other steps. The final system can be useful for speaker recognition, his emotional status etc.

Statistical Processing of Speech Features
Svozil, Martin ; Dolenský,, Jan (referee) ; Staněk, Miroslav (advisor)
This diploma thesis deals with the speech signal processing and vowel analysis mainly to uncover differences in speech features depending on the emotional state of speaker. Created application ARePa for speech signal processing was developer in Matlab environment and contains Graphical User Interface (GUI) for better manipulation with ARePa and analysed records. The application includes a complete analysis of the speech signal and further comparison of current feature with feature values from database using histograms. Of course, the developer application allows the archivation of currently analysed records into database.

Nejčastější výslovnostní chyby českých žáků v angličtině
CIHLÁŘOVÁ, Lucie
This diploma thesis deals with the most frequent errors in English pronunciation that are made by Czech students. In the theoretical part the authoress describes all the important aspects of pronunciation, factors that influence pronunciation and also some approaches to the teaching of pronunciation. Then she describes the problem sounds and some correction techniques. In the practical part the authoress evaluates what is the position of teaching pronunciation in some textbooks and which types of exercises are the most frequent. The essential part form the analysis of pronunciation errors made by pupils at middle school, the comparison with mistakes of children at elementary school and the proposal of activities that may be helpful for the removal of possible problems.

Spanish vowels in Czech students' interlanguage
Černikovská, Štěpánka ; Čermák, Petr (advisor) ; Zajícová, Lenka (referee) ; Skarnitzl, Radek (referee)
(English) The dissertation explores the vowel system of Czech L3 Spanish, focusing on three facets of its architecture: vowel quality (following SLM by Flege 1995, 1999, 2003), vowel quantity and vocalic sequences between words. Preliminary studies (Čechová 2013, 2014) suggest that there might be some evidence for the Mechanism of Equivalence in Czech L3 Spanish, since the vowel spaces of both languages consist of the same categories, with different phonetic realizations. Hence, the more similar the sounds are, the harder it is to capture the relevant difference, necessary to attain native-like pronunciation. Vowel quantity, being traditionally associated with the phonological feature of length in Czech (Palková 1994), is not present in Spanish, and compensating for that property, some Czech speakers tend to pronounce accented syllables with extraordinarily longer durations. Finally, vowel sequences in Spanish are usually subjetct to resyllabification, whereas Czech prefers glottalization to keep morphemes of words separated. These predictions were tested in 22 university Czech students with advanced level of Spanish (C1-C1). Subsequent analysis revealed consistent inclination towards L1 in terms of vowel quality, in less extent in vowel quantity, and although the prevalecent strategy for majority...
