Estimation and analysis of speech signal periodicity
Malucha, Jan ; Poměnková, Jitka (referee) ; Sigmund, Milan (advisor)
Theoretical part starts with a short introduction to speech signals and short time analysis method. Concept of periodicity is clarified. This is followed by analysis of the speech signal parameters - voiced/unvoiced classification, intonation and short time period similarity. Next the overview of methods used to analyze the mentioned parameters together with concepts of their algorithms is provided. These methods include ZCR, STE, HNR, ACF, NCC, AMDF and DTW. Algorithms using the methods with supporting preprocessing algorithms were programmed in MATLAB for practical part. All were tested on real speech signals and the results are discussed at the end of the thesis.

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.

Intonation of Czech Speakers When Speaking English
Houšť, Vítězslav ; Baumgartnerová, Alena (referee) ; Walek, Agata (advisor)
Intonace je často popisována jakožto pohyb výšek v mluvené řeči, který člověku pomáhá se slovním vyjádřením svých myšlenek. Tato bakalářská práce se zabývá možnými obtížemi s intonací, se kterými se může Čech setkat při mluvení anglicky, neboť mohou vést ke změně významu ním vyřčených slov. Cílem práce je se tyto potíže pokusit rozlišit, a to vysvětlením základních pojmů spojených s intonací, a jejich aplikací při porovnání nahrávek hlasů desíti Čechů vyslovujících osm anglických frází s nahrávkami stejných frází namluvenými čtyřmi rodilými mluvčími.

Intonation and Voice Education and Its Importance in Practice of Flute Studies.
Vaníčková, Veronika ; Saláková, Magdalena (advisor) ; Hurníková, Kateřina (referee)
The objective of this paper is to summarize the influence if intonation and vocal education on musical perception and intonational skills of musicians, and to analyze its benefits to the flute players. For example, it describes how these educations helps tuning, proper and correct breathing, formation of a tone and developing better musical images. Following research shows how this discipline can improve the quality of public performance. It also mentions briefly the flute methodology so the reader is able to understand why is voice so crucial regarding the formation of a tone when playing the flute. All the while, the work will look at parallels and differences between the fields of singing and flute playing, and their connection to intonation education. For the research part of this paper, survey of semi-structured questionnaire and extracted parts of an interview are used. In the survey itself, students and teachers of flute were asked to participate. The research on the overall attitude towards this issue is analyzed on this sample. Further it focuses on whether the students and teachers contemplate the junction of these subjects, and whether they actually use some techniques suggested by current research of this topic. The interviews offer more personal and detailed view of chosen respondents...

Intonation of a French sentence with enumeration by Czech speakers - a contrastive study
Brožová, Wanda ; Suková Vychopňová, Kateřina (advisor) ; Jančík, Jiří (referee)
1 ABSTRACT The bachelor thesis " Intonation of a French sentence with enumeration by Czech speakers - a contrastive study" describes the issue of selected prosodic phenomena of these two languages with a closer focus on intonation. The theoretical part introduces phonetics and phonology in general and subsequently presents the Czech and French phonetic systems - their segmental and suprasegmental levels. This bachelor thesis therefore describes the syllabic system and the basic prosodic elements of both languages studied. Among the basic prosodic phenomena, it describes the syllable, rhythm, rhythmic group, accent, and intonation. The practical part focuses on the analysis of intonation of Czech speakers in a French sentence with enumeration. A recording of a native speaker and a recording from the textbook (from which the sentence with enumeration was used for the recordings) are also analysed for comparison. The aim of the practical part was to find out whether native Czech speakers who speak French would follow the intonation of their native language for the given type of sentence or whether they would be proficient enough to use the intonation typical of the French language for a declarative sentence with enumeration. Through contrastive comparison and analysis using the program Praat, it was found that...

Intonation of cleft and pseudo-cleft sentences in the speech of advanced Czech learners of English
Hynková, Tereza ; Červinková Poesová, Kristýna (advisor) ; Malá, Markéta (referee)
The bachelor thesis examines the intonation of English cleft and pseudo-cleft sentences in the speech of advanced Czech ESL students. The aim of the thesis is to describe the tone choice in speech realisations of cleft and pseudo-cleft constructions produced by Czech ESL students. The first part scrutinizes literature and sets a theoretical framework for the small-scale research conducted in the second part of the thesis. The theoretical part describes the syntax of cleft and pseudo-cleft constructions, it focuses on the functional sentence perspective and provides basic information about intonation. In the second part, audio recordings are analysed in order to examine the Czech speakers' usage of tones when reading a meaningful conversation containing the target structures. It concludes that the falling tone is prevalent in the realisations of cleft sentences, whereas the productions of pseudo-clefts are more diverse. Moreover, the respondents are likely to realise three or more out of five cleft sentences using the same realisation type. They are likely to realize three or fewer out of five pseudo-cleft sentences using the same realisation type. The thesis sheds light on a marginal topic that is not popular among researchers. It compiles information on the intonation of clefts and pseudo-clefts...
