The Understood Author: A hermeneutical exploration of audiences interpretation of the author as productive practices behind a text
Pavlíčková, Tereza ; Carpentier, Nico (advisor) ; Kuzmičová, Anežka (referee) ; Hermes, Joke (referee)
in English This project builds on the tradition of audience research that theoretically and empirically established that meaning is formed in the negotiation between the text and the reader, that the audiences are agentic, their interpretation of media is contextual and situated, and that they have the potential to resist the media. It argues that it is important to explore people's attention to different sources: who is listening, to whom, and why - and asks how people understand the notion of an author that they encounter in the interpretation of factual media texts, and how this interpretation is brought back into the interpretative act. The thesis subscribes to philosophical hermeneutics as an overarching theoretical as well as methodological framework to devise a concept of an understood author that is a result of the interpretative act, where the author imagined and anticipated by the reader (in the form of prior knowledge and prejudices) is encountered and actualised by the author inscribed into the text. I carried out 28 in-depth face-to-face interviews with Czechs born between 1948-1963 to explore participants' experiences and relationship with media and media authors. Employing hermeneutical analysis, the focus is not to capture what is an author, but how it happened to be so. The...

Communication assembly for optical cableless linking
Kapuš, Martin ; Kovář, Jan (referee) ; Kolka, Zdeněk (advisor)
This Graduate Thesis is about communication module for optical wireless network. This device read data from RS232 port and two analog inputs and sends it through internet to a remote Computer. Furthermore allows voice communication between local user on module and user on remote computer. Device allows communication with standard headphones and microphone, or with Bluetooth handsfree. Basic part is microprocessor MCF5223 and Bluetooth Ezurio BISM II module. Control program has been written in C language. Printed circuit is created by EAGLE program. This device is managed via web interface and settings have been stored into EEPROM memory. Work contains description of separately parts and blocks, source code of program, description of source code and printed circuit designs.

How to make a technical speech/presentation original and impressive.
Gilyazov, Danil ; Kotásek, Miroslav (referee) ; Walek, Agata (advisor)
Velké množství učitelských technik veřejného projevu vznikla již v době kdy se lidé naučili komunikovat, toto dělá dnešní prezentaci něčím víc než pouze projevem řeči. Lidé studující lungvistiku prokázali že effectivní prezentace by se měla skládat z několika aspektů, aby zapůsobila na obecenstvo a vyvolala pocit důležitosti. V této tézy bych rád identifikoval tyto aspekty a popsal jak obecenctvo příjímá každé slovo dané prezentace.

Child Cries Detector
Sobotková, Šárka ; Jehlička, Karel (referee) ; Sekora, Jiří (advisor)
The thesis discusses the emergence of a baby cry, function and spysiological description of the vocal tract. First, the cry of children´s records scanned and made time-frequency analysis, from which it was identified in which frequensy band found the child crying. Further work includes a block diagram of the device and description of each piece. Standing position was devised in the field of soldering, and its functionality verified.

Implementation of voice activity detectors using open-source libraries in C language
Mach, Václav ; Špiřík, Jan (referee) ; Míča, Ivan (advisor)
This diploma thesis discusses the issue of Voice Activity Detection. There are two types of detectors described: energetic and statistics. Their funktionality is proved in the Matlab environment. Further, the implemetation of VADs is made through C language with standard libraries and GSL open-source libraries. The realized algorithms are compared in the scope of processing time of computation, memory management and a single mathematical operations stress. Also a comparism of the processing time according to segment length was made.

LPC Speech Coding
Zapletal, Ondřej ; Kyselý, František (referee) ; Rajmic, Pavel (advisor)
The contents of the thesis "LPC speech coding" are studies of this method of a parametric source coding, explanation of mathematical procedures that are used in it (linear prediction, autocorrelation, Levinson-Durbin algorithm, transfer to a form suitable for transmission, Chebyshev root searching polynomial method) and acquaintance with the signification and application of that method in real speech encoders. The task of the original project of this thesis is a description and simulation of a simple speech encoder based on LPC, which transforms a real speech signal into a bit flow, which contains all of the significant parameters for its backward reconstruction (LSF coefficients, pitch period, excitation level, voice detection - AMDF method). One part of this thesis is a discussion about currently used speech encoders.

Converged solution of speech services
Mácha, Tomáš ; Kovář, Petr (referee) ; Novotný, Vít (advisor)
Development in VoIP technology is connected with the rapid growth of quality and data rate of the Internet connection. The application of the VoIP technology has become one of the key areas in telecommunication and networking. The main task of this thesis was to explore the questions of IP telephony and voice transmission over data networks according to H.323, SIP and Cisco architectures. Next focus was on designing and implementing experimental workplaces of mentioned architectures and their converged solutions. The purpose of the first chapter is to introduce the theory background of architectures required for implementation of real-time services in data networks and their comparison. The key objectives of the second and third part are to design and implement experimental workplaces containing signaling and proxy servers and hardware or software IP phones of several architectures. Illustration examples of different network topologies are included to demonstrate designed and realized VoIP solutions. Several tests of established communication are done using a packet analyzer. These tests examine duplex data transmission over IP. This article also contains two laboratory exercises designed according to gained practical experiences. The laboratory exercises provide an overview of theory and clearly indicate the possibilities of IP telephony.

Agreements and Disagreements between Automatic and Human Speaker Recognition
Valenta, Jakub ; Matějka, Pavel (referee) ; Rohdin, Johan Andréas (advisor)
Tato práce se zabývá problémem rozpoznáváním mluvčího. Uvedený pojem je definován a doplněn o jednotlivé metody, které s ním souvisí. Cílem práce je poukázat na shody a rozdíly mezi lidským a automatickým procesem rozpoznávání mluvčího. V úvodu práce jsou popsány teoretické poznatky z obou zmíněných oblastí, tj. na jaké aspekty lidské řeči se zaměřuje člověk, resp. automatický systém. Následně je provedeno několik experimentů, které mají za úkol srovnat tyto dvě metody. Tyto experimenty jsou vyhodnoceny tak, že je možné pozorovat, které testovací úlohy dokáže lépe vyřešit člověk, aby následně bylo možné tyto poznatky použít ke zlepšení funkce automatického systému. V závěru práce je takovýto návrh na zlepšení automatického systému předveden a otestován. Testování proběhlo úspěšně a byla zaznamenána vyšší přesnost při vyhodnocování. Takový výsledek tedy může být užitý v dalších výzkumech a umožnit tak další vývoj v oblasti automatického rozpoznávání mluvčích.
