Object Oriented Library for Controlling an e-Puck Robot
Plátek, Ondřej ; Mráz, František (advisor) ; Černo, Peter (referee)
E-Puck is an educational robot with differential drive and it is sufficiently equipped with sensors. The result of present thesis is the C# object oriented Elib library, which allows to control an e-Puck robot from a host computer over the Bluetooth wireless technology. The model examples in the TestElib console application presents the usage of the Elib library in program for the e-Puck robot. Moreover, it offers a comfortable system of help and documentation. Enclosed sets of tools allows more effective debugging of programs, which use the Elib library.

Data-driven Pronunciation Generation for ASR
Obedkova, Maria ; Plátek, Ondřej (advisor) ; Peterek, Nino (referee)
Data-Driven Pronunciation Generation for ASR Maria Obedkova In ASR systems, dictionaries are usually used to describe pronunciations of words in a language. These dictionaries are typically hand-crafted by linguists. One of the most significant drawbacks of dictionaries created this way is that linguistically motivated pronunciations are not necessarily the optimal ones for ASR. The goal of this research was to explore approaches of data-driven pro- nunciation generation for ASR. We investigated several approaches of lexicon generation and implemented the completely new data-driven solution based on the pronunciation clustering. We proposed an approach for feature extraction and researched different unsupervised methods for pronunciation clustering. We evaluated the proposed approach and compared it with the current hand-crafted dictionary. The proposed data-driven approach could beat the established base- lines but underperformed in comparison to the hand-crafted dictionary which could be due to unsatisfactory features extracted from data or insufficient fine tuning. 1

Rozpoznávání řeči pomocí KALDI
Plátek, Ondřej ; Jurčíček, Filip (advisor) ; Peterek, Nino (referee)
The topic of this thesis is to implement efficient decoder for speech recognition training system ASR Kaldi (http://kaldi.sourceforge.net/). Kaldi is already deployed with decoders, but they are not convenient for dialogue systems. The main goal of this thesis to develop a real time decoder for a dialogue system, which minimize latency and optimize speed. Methods used for speeding up the decoder are not limited to multi-threading decoding or usage of GPU cards for general computations. Part of this work is devoted to training an acoustic model and also testing it in the "Vystadial" dialogue system. Powered by TCPDF (www.tcpdf.org)

Development Environment Extending the Dialog Management Options of AIML
Brodec, Václav ; Kuboň, Vladislav (advisor) ; Plátek, Ondřej (referee)
The AIML language was created with a goal of authoring of simple chat bots. Therefore it lacks some of the features of advanced dialog systems. One of them is the support for dialog management, which is beneficial in many applications that the language has already spread into due to its popularity. This thesis solves the problem of dialog management implementation in pure AIML by using the augmented transition networks in design and code generation. It results in a development environment that supports the chosen solution, thus facilitating the design of more complex bots, while maintaining compatibility with standard interprets.
