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.

Linear prediciton and cepstral synthesis of speech signal in the TTS system
Mekyska, Jiří ; Stejskal, Vojtěch (referee) ; Smékal, Zdeněk (advisor)
This work deals with a linear prediction and cepstral synthesis of speech signal in the TTS (Text-to-Speech) systems with the opportunity of modeling the prosody. The work contains a description of speech signal in acoustic and phonetic plane, the principle of speech production and the way we can figure the speech signal in time and frequency domain. Next, there is the TTS block structure mentioned, whereas each block has its own detailed description. In the work, the modeling of prosody using the three most important suprasegmental features (fundamental tone, continuation and speech intensity) is also described. At the end of this work, there is a design and realization of universal Czech TTS system which is based on the speech synthesis in frequency domain. This system is implemented in program MATLAB.

The Professional Speech and Slang of Musicians
NYKRÝNOVÁ, Markéta
The analysis of musicians{\crq} professional speech is the subject of this thesis. The main stress is put to the profiling of various ways the professional speech vocabulary is being enriched: by taking over expressions from foreign languages, semantic forming of lexical units (metaphor, metonymy) and creation of new words. Therefore, the attention is also focused on the word-building structure of the lexical units. Also, the presence or absence of the expressive token is being observed. The goal of the work is to draw attention to the vocabulary of musicians{\crq} professional speech from the linguistical point of view. The explanatory directory of terms used by musicians during excercise of their profession is the integral part of the work. For easier orientation, the index is also included.
