Emotional State Recognition and Classification Based on Speech Signal Analysis
Černý, Lukáš ; Atassi, Hicham (referee) ; Smékal, Zdeněk (advisor)
The diploma thesis focuses on classification of emotions. Thesis deals about parameterization of sounds files by suprasegment and segment methods with regard for next used of these methods. Berlin database is used. This database includes many of sounds records with emotions. Parameterization creates files, which are divided to two parts. First part is used for training and second part is used for testing. Point of interest is self-organization network. Thesis includes Matlab´s program which can be used for parameterization of any database. Data are classified by self-organization network after parameterization. Results of hits rates are presented at the end of this diploma thesis.

Kohonen network
Kaňa, Michal ; Hynčica, Tomáš (referee) ; Jirsík, Václav (advisor)
The problems with artificial neuron systems, or, more precisely, with self-organising neuron systems and their usage, have been concisely described in this Bachelor's thesis. The thesis is more deeply concerned with the Kohonen self-organising system and describes the principle of its study and programmes for its simulation. The practical part of the thesis concerns the problem of regulating initial neuron weights in the Kohonen system and their effect upon the final position of the surviving neuron. This effect is demonstrated in the selected experiment set with the help of the programme MATLAB.
