Support of the language development through the stimulation of auditory perception at early childhood
Machová, Martina ; Korandová, Zuzana (advisor) ; Klenková, Jiřina (referee)
The main topic of the bachelor thesis supports the development through the stimulation of auditory perception in early childhood. The thesis consists of three chapters, two of them are theoretical and the last one is practical. The theoretical part of the bachelor thesis defines basic terms such as speech, language, and communication. Further, it describes the ontogenesis of speech, language and communication in early childhood. The ontogenesis of speech, language and communication is described by two different authors. The next chapter of the theoretical part introduces auditory perception. This chapter also includes a description of the anatomy and physiology of the ear, auditory perception development, and areas of auditory perception. The research part of the bachelor thesis is research based on qualitative methods. The research method used in the bachelor thesis is case studies. Case studies were processed with the help of other research techniques. The main aim of the research is analyzation of the development of auditory perception in early childhood in one private kindergarten in Prague. To achieve the main aim, the subgoals of the bachelor thesis and the research questions have been defined. The research elaborates on the five case studies of children in early childhood. The research part...

Possibilities for the development of partial functions in children with developmental language disorder in preschool age
Selingerová, Pavlína ; Horynová, Jana (advisor) ; Klenková, Jiřina (referee)
The topic of this bachelor thesis is the possibilities of development of partial functions in children with developmental language disorder in preschool age. The thesis is structured in four chapters, three theoretical and one practical. The first chapter is devoted to the description of the preschool child and is divided into subchapters that introduce ontogenetic speech development, impaired communication skills and school maturity. The second chapter deals with developmental language disorder and includes aetiology, symptomatology, diagnosis and speech therapy. The third chapter defines the concept of sub-functions and lists the different areas such as auditory perception, visual perception, motor skills, thinking, attention, memory, speech, language and communication. The fourth chapter, the practical part of the bachelor thesis, includes case studies of children with developmental language disorder in preschool. It describes the personal and family history, preschool education, speech therapy intervention and the level of partial functions, which includes my own work with children. The aim of the practical part of the bachelor thesis is to analyse the possibilities of development of sub-functions in children with developmental language disorder in preschool age. The sub-objectives are to...

Childrens´ speech development with speech defects in preschool age
MALÁ, Petra
This Bachelor thesis on the topic of the Development of Speech in Preschool-aged Children with Logopedic Speech Impairments aims to analyze the development of speech in two children with logopedic impairments by means of observation in a set timeframe. The theoretical part of the thesis describes the regular process of a child's development during the preschool years, as well as the regular development of speech. It also addresses existing logopedic impairments, their causes, their manifestations, and reeducation procedures. The practical part of the thesis is supported by research conducted listening in at two preschool institutions. It contains the case studies of the children observed and evaluates the development of their speech in a given timeframe.

Multimedia support of the course BSIS
Pasečný, Jan ; Šebesta, Vladimír (referee) ; Sigmund, Milan (advisor)
This paper takes aim at creating a consistent form of study materials, supplemented with illustrative examples, for Signals and systems subject. The thesis starts with basic characteristics of acoustic, image, biological and communication signals. Characteristics of linear signals and AD&DA conversion has been added to the next part and to complete the submission, discrete signals follow. Diploma thesis as a whole contains basic theoretical description of problematics, which it tries to supplement with interesting examples, connections, graphs and matlab scripts for illustrative presentation of mentioned problematics.

State of the art speech features used during the Parkinson disease diagnosis
Bílý, Ondřej ; Smékal, Zdeněk (referee) ; Mekyska, Jiří (advisor)
This work deals with the diagnosis of Parkinson's disease by analyzing the speech signal. At the beginning of this work there is described speech signal production. The following is a description of the speech signal analysis, its preparation and subsequent feature extraction. Next there is described Parkinson's disease and change of the speech signal by this disability. The following describes the symptoms, which are used for the diagnosis of Parkinson's disease (FCR, VSA, VOT, etc.). Another part of the work deals with the selection and reduction symptoms using the learning algorithms (SVM, ANN, k-NN) and their subsequent evaluation. In the last part of the thesis is described a program to count symptoms. Further is described selection and the end evaluated all the result.

Modern coding of speech signals using overcomplete models
Zapletal, Ondřej ; Průša, Zdeněk (referee) ; Rajmic, Pavel (advisor)
The theoretical contents of this thesis are studies of overcomplete models. Those are the models of signals, on which is set for their parametrization more variables, than it's necessary and consequently there's computed so-called sparse solution via iteration algorithms. A goal of this analysis is a selection just of the considerable (sparse) parameters. The theory is based on a linear algebra, vector spaces, bases and so-called frames. The task of the individual project of this thesis is a description and simulation of two speech coders: a classical coder based on linear predictive speech coding and a coder, that's making use of overcomplete stochastic ARMA processes models. A part of their realization is to simulate their decoders and a analyze their reconstruction quality. For their realization there is used MATLAB and an overcomplete models' library (toolbox frames).

Speech segmentation
Andrla, Petr ; Míča, Ivan (referee) ; Sysel, Petr (advisor)
The programme for the segmentation of a speech into fonems was created as a part of the master´s thesis. This programme was made in the programme Matlab and consists of several scripts. The programme serves for automatic segmentation. Speech segmentation is the process of identifying the boundaries between phonemes in spoken natural languages. Automatic segmentation is based on vector quantization. In the first step of algorithm, feature extraction is realized. Then speech segments are assigned to calculated centroids. Position where centroid is changed is marked as a boundary of phoneme. The audiorecords were elaborated by the programme and a operation of the automatic segmentation was analysed. A detailed manual was created to the programme too. Individual used methods of the elaboration of a speech were in the master´s thesis briefly descripted, its implementations in the programme and reasons of set of its parameters.
