Effect of alcohol on speech signal
Kandus, Filip ; Tučková, Jana (referee) ; Sigmund, Milan (advisor)
The main theme of the thesis is to examine the influence of alcohol on the speech apparatus and speech signal. The first part is focused on symptoms and detection of alcohol concentration in the human body. The following part describes somescientific publications and projects, which dealt witha a similar theme. Also the czech documentation to german database ALC was created. Based on phonetic knowledge, Czech text was compiled. Different speakers were reading this text so we go tour own database of alcoholic and sober speech. Samples from individual speakers are processed using linear prediction, formant and cepstral analysis in MATLAB and the effect of alcohol on selected parameters of speech signal is evaluated.

NNLab - platform base for text-to-speech synthesis
Santarius, J. ; Tučková, Jana
Prosody modelling in synthetic speech is one of the possible applications of artificial neural nets (ANN). The training and testing files for prosody modelling by ANN must be large; therefore it is useful to automatize the process. The modular program system NNLab is a powerful tool for an easy-to-operate ANN system for prosody modelling of synthetic speech. In the center of NNL environment is a database that contains data that characterize the ANN. The system is done in MATLAB, V5.2, NN Toolbox V2.O.

Fundamental frequency and duration modelling by neural networks
Tučková, Jana
This contribution presents the application of a neural network for the fundamental frequency (F.sub.0./sub.) determination and for the modeling of phonemes duration. The minimization of the number of input parameters and the reduction of the structure redundancy is described. The pruning method of artificial neural networks is s suitable tool.
