The aim of this diploma thesis is to analyze some of the acoustic characteristics of German fricatives [x] and [ ] and Czech fricative [x]. These sounds will be described and compared partly on the basis of spectral qualities of their noise, expressed by the so-called spectral moments (see chap. 3), and partly on the basis of their temporal characteristics. We assume to find a co-articulatory influence of the preceding vowel on the spectral characteristics of a fricative. We further assume that potential differences in values of the spectral moments, which can be, to a certain extent, considered an acoustic correlation of the place of articulation, can demonstrate a slightly different place of articulation of Czech and German velar fricatives. Using a perception test, we will attempt to explore a possible relation of German "Ich-laut" in the speech of German students of Czech to spectral mean values. The spectral moment measurements along with the perception test results may be found useful in teaching German as a second language for improving one's pronunciation. In practise, it can lead to an improvement in accepting a foreign speaker as an efficient user of the language.
