Development of an IoT System for Home Appliances
Vančo, Timotej ; Kaczmarczyk, Václav (referee) ; Lázna, Tomáš (advisor)
The aim of the bachelor thesis is to make a research of the current state of IoT and then propose the creation of my own IoT solution for smart home. It also aims to select the appropriate components for the custom solution from which the system will compose and design an appropriate communications interface with option to secure communicate with each other. Then revive the hardware of sensor modules, actuators and control system. The system should be capable of displaying measured data and enabling actuators to control. The final goal is to control the system with voice commands. The theoretical part is focused on description of what is IoT, history, usage and near future of IoT. Furthermore, the currently used IoT classifications and IoT systems in smart homes are described from a commercial and open-source perspective. The theoretical part ends with the comparison of voice assistants and the way the text is understood by the computer. The practical part deals with the description of own solution, selection of components for modules, creation of printed circuits, designing boxes for 3D printing, creation software for individual modules for measurement, communication and control of intelligent home. Next, I am writing about a system that displays measured values from modules, creates a user interface, and controls action members using buttons or voice commands.

Using of voice for home eguipment control
Bubla, Lukáš ; Vojáček, Zdeněk (referee) ; Lacko, Branislav (advisor)
The bachelor thesis is focused on home automation, specifically on voice control. It describes methods of communication and control of automated systems and especially problematics of computer voice recognition using different methods. The thesis displays specific product for voice controlling developed by Czech company Elko ep, s.r.o. and then briefly looks at the issue of gesture control. At the end compares product from Elko ep with other products from foreign companies and discuss advantages and disadvantages of voice or gestures control.

Dental status in handicapped patients
Chleborád, Karel ; Dostálová, Taťjána (advisor) ; Racek, Jaroslav (referee) ; Hanzlíček, Petr (referee)
The information in the medical records serve many purposes: they can be used for diagnosis and therapy, medical documentation contains information that can be the basis for financial authorities for treatment or for pumping reimbursement from health insurance. The data can be used in statistics and other scientific purposes. The aim of study is to verify the simplicity of data process implementation and time of data storing for modification of classical paper WHO dental card, lifetime dental EHR controlled by keyboard and lifetime dental EHR controlled by voice. All three methods were applied on 126 patients. At first the patients were inspected by a standard technique (communication between dentist and nurse) and the data recorded into the paper WHO dental card. The same person recorded all data to lifetime dental EHR using keyboard and using voice. Then we compared the time, which was needed for recording the data using these three methods. Using Friedman test we found very significant differences in time of recording among three methods (p<0.001). We can see that the paper WHO dental card was recorded quickly, but its rise due to missing electronic form is difficult. Times for recording data using keyboard or voice in lifetime dental EHR were not significantly different. The clinical practice...

Hlasové ovládání pro efektivní editaci textu
Citorík, Juraj ; Lokoč, Jakub (advisor) ; Skopal, Tomáš (referee)
The aim of this thesis is to provide a comprehensive introduction to digital sound processing and speech recognition. Selected speech recognition features as well as algorithms are introduced and utilized in a voice controlled text editor and a .NET class library. The performance of the features is evaluated in both speaker-dependent and speaker-independent recognition of commands related to text editing. The library provides a straightforward way of implementing a speaker-dependent, domain-constrained voice recognition in an arbitrary application. It is used in a simple voice controlled text editor. The editor allows the user to assign voice commands to built-in actions. In this way, it is possible for inexperienced users to access and use advanced features of the program without having to learn complex workflows. Moreover, this approach is language-agnostic and can even be used by people with speech impairments as opposed to majority of presently used voice recognition systems. The results of the experiments indicate that, given a recording of sufficient quality, the presented features and algorithms provide an effective means to implement a speaker-dependent speech recognition system, which can be used in a voice controlled text editor.

Voice command for a TV set
Černý, Patrik ; Straňák, Pavel (advisor) ; Peterek, Nino (referee)
Title: Voice command for a TV set Author: Patrik Černý Department: Institute of Formal and Applied Linguistics Supervisor: Mgr. Pavel Straňák, Ph.D. Abstract: A goal of this thesis is to create television voice control intended for poeple with speech and movement disorder. This is achieved by interconnecting computer and television. Voice control is based on well-known dynamic time warping algorithm. It has been shown, that due to high and frequent changes in sound intensity the voice control of television is quite a complex task. The word recognition success rate of the final application is not very high, but for the purpose sufficient. Because of application design, program can be easily extended by techniques, that can improve recognition effectivity. Keywords: voice control, word recognition, dynamic time warping, television 1

Voice Controlled Calculator
Pavelek, Ota ; Szőke, Igor (referee) ; Grézl, František (advisor)
This thesis describes implementation of calculator, which can be controlled by both voice and normal way. Speech recognizing is realized with BSCORE library and has recognition network restricted to words needed by calculator. When the recognition is done, recognized sentence is transformed to expression and shown to user, so it can be corrected (especially in case of erroneous recognition). Expression is evaluated on user's request. The purpose of voice control is to make usage of calculator more effective and accesible for handicapped users.

Voice Controled Map of FIT
Huták, Petr ; Grézl, František (referee) ; Szőke, Igor (advisor)
This bachelor's thesis describes the design and developement of navigation system for the Faculty of information technology, Brno university of technology with voice control. It explains the methods used for finding the shortest path on the map, speech recognition and describes existing navigation systems with voice control. The thesis is focused on creating a user interface with voice control. The purpose of voice control is to make usage of this navigation system more accesible and effective in a public place. Speech recognizing is realized with BSAPI library.

Computer voice control
OSTRÝ, Lukáš
Today, it is placed increasing emphasis on alternative communication with the computer. Voice control is probably the easiest way to control your computer, for those who do not have somehow equipped. Word of equipment are meant groups of people for whom traditional communication with computers inappropriate. The main groups are physically and mentally disabled, children and old people. For disabled and elderly people a problem is physical disabilities such as blindness, or a problem with the limbs. In children and mentally handicapped is a problem in the complexity of control. Voice control is nowadays no longer technically possible, but still appears more interested in the subject. It would therefore be advantageous to start teaching this issue in primary schools and help expand interest in this issue.
