"Fundamental frequency extraction method using central clipping and its importance for the classification of emotional state"@en . . . "The paper deals with a classification of emotional state. We implemented a method for extracting the fundamental speech signal frequency by means of a central clipping and examined a correlation between emotional state and fundamental speech frequency. For this purpose, we applied an approach of exploratory data analysis. The ANOVA (Analysis of variance) test confirmed that a modification in the speaker's emotional state changes the fundamental frequency of human vocal tract. The main contribution of the paper lies in investigation, of central clipping method by the ANOVA."@en . . "Mikulec, Martin" . "[0FD2360CB8C4]" . . "Partila, Pavol" .
