Application for the calculation of speech features describing hypokinetic dysarthria
Hynšt, Miroslav ; Mekyska, Jiří (referee) ; Kiska, Tomáš (advisor)
This thesis is about design and implementation of application for computing speech parameters on people with Parkinson disease. At the beginning is generaly described Parkinson disease and Hypokinetic dysarthria and how it affects the speech and speech parameters when it occurs. Mainly there are described areas of speech like phonation, prosody, articulation and fluent speech. As a part of next topic this thesis describes specific speech parameters with bigger meaning during diagnosis Parkinson disease and it's progress over the time. There are also mentioned few significant studies dealing with examination of speech of the subjects with diagnoses of Parkinson disease and computing some speech parameters in order to analyze their speech impairments. Part of the thesis is description of implemented standalone application for calculating, exporting and visualizing of speech parameters from selected sound records.

Application of Fluid-structure Interaction on Oscillating Human Vocal Folds
Meisner, Patrik ; Švancara, Pavel (referee) ; Hájek, Petr (advisor)
The presented thesis is involved in the biomechanics of phonation. The aim of the thesis is to set a fluid-structure interaction between the vocal folds and air flow when the pressure from lungs reaches the physiological values. In the expected outcome the self-oscillating vocal folds should be observable with characteristics shape-shift from convergent to divergent. In theory part of the thesis is described Anatomy of the vocal tract, physiology of the human phonation, research of computational simulations, experiments and visualisation methods are described in the theory part of the thesis. In the second part, setup of computational simulation with the finite element method is presented. Besides of the fluid-structure interaction the acoustical model is set. Achieved results are presented and compared to the results in literature. Displacements are evaluated from the structural model and pressures, velocities and flow velocities are evaluated from fluid model, so as acoustics results.

Sub-types of hypokinetic dysarthria in patients with moderete Parkinson's disease
Adamják, Adam ; Kováč, Daniel (referee) ; Mekyska, Jiří (advisor)
This final thesis deals with the research of Parkinson's disease, hypokinetic dysarthria, and acoustic and statistical analyses. Hypokinetic dysarthria is a speech disorder that is a typical manifestation of Parkinson's disease, a neurodegenerative disease that affects approximately 2% of the population over the age of 65. The aim of this work is to reveal the subtypes of hypokinetic dysarthria, based on clinical parameters, acoustic analysis, and statistical analysis. In the acoustic analysis, parameters that examine the area of phonation, prosody, articulation, and speech tempo have been implemented. Subsequently, a statistical analysis was processed, thanks to which it was possible to reveal the subtypes of hypokinetic dysarthria.

Demands of the Teacher's Proffesion on the Teachers' Voice
Králová, Michaela ; Tichá, Alena (advisor) ; Koverdynský, Luděk (referee)
This dissertation thesis deals with the demands on teachers' voice and proper use of voice in the teacher's profession. The whole thesis consists of two parts: theoretical and practical. The theoretical part is divided into nine sections: the anatomy and physiology of the vocal tract, voice developement, comparison of spoken and singing voice, psychological impact on voice, voice defects and hygiene, voice reeducation, methods of voice diagnostics and voice acoustics. The research part presents the findings of acoustic voice measurement. Students (only women) of Faculty of Education in Prague participed in the research. The objective of this part was to asses the quality of students' voice and their voice readiness for future teaching.

Comparison of postural function meaning of the preschool children singing expression
Malá, Daniela ; Koverdynský, Luděk (advisor) ; Tichá, Alena (referee)
The diploma work is dealing with an influence of postural muscles on preschool children singing expression as weel as on connection between a posture and a breathe. The aim of this diploma work is not just a clarification of this issue, but primaliry it is an aspiration of creating a methodology of exercises, which leads to an improvement of children`s singing. Experimental part of this diploma work is concerned with a verification of created methodology on constant group of preschool children. An audio CD with records of children singing expressions, which confirms reached verdicts, is included.

Influence of airflow control with vocal cords on dynamic stand stabilization
Rybáčková, Kristýna ; Šorfová, Monika (advisor) ; Lopot, František (referee)
Title: The effect of airway control on stance dynamic stability Objectives: The aim of this thesis is to find out whether and how will the influence of vocal cords modulation be manifested on the dynamic stabilization of the standing body during translational shifts of the supporting surface of different intensities and A-P directions. Thus, building on the findings of Massery et al (2013). Methods: The thesis has the character of qualitative research. The experiment was attended by 23 healthy probands, of which 7 men and 16 women aged 20-40 years. Spirometry was used to test the objectivity of airway airflow during breathing / phoning maneuvers with different vocal cords positioning and dynamic computer posturography using the Neurocom Smart Equi Test System and its Motor Control Test, which evaluated the effectiveness of automatic postural responses. We connected the posturograph with the spirometer using the Kistler accelerometer (type 8766A100BB). The course of the experiment was simultaneously recorded by a camera (GoPro Hero 7). The Smart EquiTest System generated three postural perturbations of different intensity (S - sub treshold, M - threshold, L - saturating) in two directions (anterior translation / posterior translation). The measured data were then processed in the program Neurocom...
