Summary: | The present thesis has been based on numerous surveys testifying the differentiation of the global speaking fundamental frequency characteristics according to the language, or the dialect, of the user and attempts to put them to the test in the Polish-Czech context. The research was divided in two parts: monolingual and bilingual. In both phases we analysed 64 and 42 recordings of 64 speakers in total, i.e. 43 Czechs (18 females and 14 males) and, by analogy, 32 Poles. All the recordings were obtained at the Phonetics Laboratory of the Institute of Phonetics FF UK in Prague. The subject matter of our description was the values of the alternative baseline as the most suitable representative of neutral tendencies of the global frequencies of the individual's F0. The analysis has been aimed at testing the alternative hypothesis, which presupposes the existence of differences in the fundamental frequency of Czech and Polish speakers, in particular in the higher values of Polish speakers. The basic monolingual phase of the research has proved a higher F0 value of the Polish sample in all the cases. The difference within the selective group of males has reached the highest degree of significance with the probability of its existence within the whole population being 89% (p > 0.11). After we took an unexpected...
