An analysis of prenuclear accents in read speech is carried out with the aim of finding instances of regularity in their distribution. Significant differences are identified with respect to position within the phrase and phrase length, some of which are correlated with declination and pitch span narrowing. Only a weak interaction is found between nuclear and prenuclear pitch accents. No tendency of using only one type of pitch accents in a phrase could be found. The autosegmental approach seems to be a viable means of analyzing prenuclear intonation in Czech.
