State of the art speech features used during the Parkinson disease diagnosis
Bílý, Ondřej ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
This work deals with the diagnosis of Parkinson's disease by analyzing the speech signal. At the beginning of this work there is described speech signal production. The following is a description of the speech signal analysis, its preparation and subsequent feature extraction. Next there is described Parkinson's disease and change of the speech signal by this disability. The following describes the symptoms, which are used for the diagnosis of Parkinson's disease (FCR, VSA, VOT, etc.). Another part of the work deals with the selection and reduction symptoms using the learning algorithms (SVM, ANN, k-NN) and their subsequent evaluation. In the last part of the thesis is described a program to count symptoms. Further is described selection and the end evaluated all the result.

Pronunciation of consonantal clusters in the Czech speech of Spanish speakers
Pugachova, Kateryna ; Veroňková, Jitka (advisor) ; Škodová, Svatava (referee)
The topic of this thesis belongs to the area of L2 acquisition. It focuses on the Czech as a second/foreign language for native Spanish speakers, specifically on their pronunciation of selected consonantal clusters in comparison with the Czech orthoepic norm. The theoretical part summarizes the problems learning the pronunciation of second/foreign language and describes phonetic systems, syllable structure and specific combinatorial properties of sounds in Czech and Spanish. The practical part describes the research for which thirteen Spanish speakers from different countries and with different length of stay in the Czech Republic were recorded. For the purpose of the research a special text containing the selected consonantal clusters in initial, medial and final position of the word was compiled. Words were examined with a perceptive analysis and the results were processed according to established criteria.

Consonantal and vocalic differences in Czech English with reduced and enhanced foreignness
Pojarová, Veronika ; Volín, Jan (advisor) ; Weingartová, Lenka (referee)
The objective of this thesis is to identify those features of the Czech accent in English that are the most salient in the perception of the Czech listener and that may disturb the communication process. The purpose of the introductory chapter is to familiarize the reader with the subject of the foreign accent, to provide a brief summary of the current state of research and to introduce a series of empirical studies. The research part of the thesis analyzes the individual realizations of the selected speech sounds /θ, ð, ŋ, r, w, æ, ɜː/ and ventures to draw meaningful conclusions from the results. The material analyzed consists of a total of 3568 speech sound tokens, recorded by 9 male and 19 female speakers. Each respondent produced two recordings, one in the British standard mode and another where the speaker imitated the Czech foreign accent. The 3568 tokens were individually rated and the two modes were then compared for each speaker. The results showed /r/ to be favoured by the largest number of speakers as an indicator of the Czech accent, while /θ, ð, ŋ/ often had the same rating in both modes. However, additional factors such as speaker proficiency and number of tokens from individual speech sounds must be taken into consideration before any final conclusions can be drawn from the raw data....

English Pronunciation of Middle School Children
ŠIMŮNKOVÁ, Radka
The main content of my diploma thesis is Pronunciation of middle school children. The theoretical part deals with the aims of pronunciation teaching. This part concerns the question to what measure the pronunciation is important and whether it is possible to influence it by teaching process. Furthermore, I attended to pronunciation differences between English and Czech sounds and typical mistakes made by Czech pupils. The practical part searches and analyses mistakes in Engish pronunciation made by pupils who have just come to middle school by research scanning. Consequently I suggested several exercises to eliminate some of the ascertained mistakes. At the end, I also practically verified them in school practise and summed them up in my final reflection.
