Abstract
The paper analyses the intonation of syllables in broadcasted communication utterances (analyzing audio samples from radio programs Rádiožurnál and Literárna revue Rádia Slovensko) from theoretical point of view, while building upon the outcomes of the experimental phonetic research. Duration of the individual segments, intensity of sonantic cores including intensity of syllables and basic frequency F0 were analysed. Role of the analysed parameters in relation to the sonic formation of the text can be seen in exact graphs, which are cross-referenced by the measured values. The analysis has shown that an intonation differentiation of text-forming features in the broadcasted communication utterances is significantly influenced by tonal modulation (melody). Variation potential of time modulation is limited by faster pace of broadcasted texts. The strength modulation is demonstrably limited by signal standardization in radio broadcasting.
