Detection of speech disorders
Struhař, Michal ; Rajmic, Pavel (referee) ; Sysel, Petr (advisor)
This thesis deals with detection of speech disorders. One of the aims of this thesis is choosing suitable parameterization: short-time energy, zero-crossing rate, linear predictive analysis, perceptual linear predictive analysis, RASTA method, cepstral analysis and mel-frequency cepstral coefficient can be chosed for detections. Next aim is construction of detector of speech disorders based on DTW (Dynamic Time Warping) and artificial neuron network. Single detection proceeds on the base of collected tokens from chosen analysis and phonetic transcription of speech. Analyses, detector and phonetic transcription of Czech language are implemented in simulation environment of MATLAB.

Acoustic analysis of poem recitation in patients with Parkinson's disease
Mucha, Ján ; Smékal, Zdeněk (referee) ; Galáž, Zoltán (advisor)
Diploma thesis is focused on the acoustic analysis of poetry recitation in patients with Parkinson's disease. This disease is associated with speech disorder called hypokinetic dysarthria. One objective of this thesis was familiarization with process, symptoms and treatment of these diseases. In thesis is described preprocessing and parametrization of the speech signal and the binary classification methods. Subsequently, it is the above proposal modular system of auto-diagnosis of Parkinson's disease based on acoustic analysis of the speech. The proposed system is implemented in MATLAB. Classification of calculated parameters is realized using the method of Random forest and Support vector machine. The results of these methods are compared and listed in the thesis. The main objective and the result of this thesis is a system of automatic diagnosis of Parkinson's disease based on acoustic analysis of the poem recitation.

Logopedic defect analysis and recognition in speech utterances
Diviš, Jan ; Atassi, Hicham (referee) ; Smékal, Zdeněk (advisor)
This bachelor's thesis deals with logopaedia mistake called dyslalie and its characteristics. I described the process creation and representation of speech. There are presented bases of processing and analyses speech signal ( LPC, cepstral, MFCC). I presented characteristics of speech and calculation of LPC, cepstral and Mel-frequency cepstral coefficients in the programme MATLAB. The bachelor's thesis includes problems of incorrect pronunciation sound "r" and "ř".

Voice Conversion
Lukáč, Peter ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
Predmetom tejto práce je konverzia hlasu. Konverzia hlasu predstavuje preberanie reči jedného rečníka, ktorého nazývame zdrojový rečník a transformovanie tejto reči na reč ktorá znie ako reč druhého rečníka, ktorého nazývame cieľový rečník. Toto je dosiahnuté pomocou systému pre konverziu hlasu, ktorý je popísaný v tejto práci. Ako framework pre analýzu a syntézu reči používame STRAIGHT, ktorý bol dominantne používaný vo Voice Conversion Challenge 2016. Náš system pre konverziu hlasu je založený na konverzii spectra použitím doprednej neurónovej siete a paralelného trénovania.

Removal of a Known Signal from a Recording
Urbánek, Radomír ; Žmolíková, Kateřina (referee) ; Černocký, Jan (advisor)
The goal of this diploma thesis is to design and implement method for removing known signal from recorded sound. In the introductory part of the thesis are described the properties of sound and its propagation through the space, digital signal processing on the computer and the computing of the system impulse response. The sequential development of the methods leading to the removal of the known signal from the recording is described further. The following part contains a description and implementation of this method. It also describes how and at what data the method will be tested. Finally, testing is evaluated, improvements and further possible work is proposed.

Detecting Stress in Speech
Šoltés, Samuel ; Beneš, Karel (referee) ; Grézl, František (advisor)
Stress influences people in several ways and can lead to decrease in performance and / or critical mistakes. Stress detection in speech measures the influence of stress in speech. The goal of this thesis is to offer a closer look at the impacts of stress, choose adequate parameters of speech which would manifest these impacts, implement their estimation and compare their results. The thesis contains description of stress and its effects on humans; glottal pulse, spectrum, fundamental frequency and formants as the parameters chosen for stress estimation; design and implementation of parameter value estimation from speech signal and obtained values of given parameters on two different databases.

Analysis of the speech profile of David Rath presented by Czech audiovisual media
Švejkovský, Jakub ; Just, Petr (advisor) ; Klabíková Rábová, Tereza (referee)
The aim of this diploma thesis is to analyze the rhetorical profile of one of the most prominent Czech rhetors after the Velvet revolution, physician and politician David Rath. In the theoretical part, the author comprehensively processes the history of public speaking based on the ancient but still current rhetorical tradition of ancient Greece and Rome. Furthermore, the work describes all the specifics defining both the interpersonal communication itself, as well as its individual aspects - specifically, verbal, nonverbal and psychological components, along with persuasive and manipulative techniques. The practical part is co-created by two key aspects - the career and political profile of David Rath and the analysis of his speech. The theoretical basis in combination with the knowledge of the life story of the central speaker forms the basis and context for the analysis of Rath's rhetoric. On carefully selected speeches, the author then examines in detail how the observed rhetor can adapt to various situations across the communication spectrum. The researched findings can then be used for further analyses of a similar focus.
