In this paper a longitudinal study is presented of age-dependent speech acoustic characteristics from the utterances of Czech actresses, acquired from movie databases recorded in the years from 1985 to 2014. The age dependence of phonation is analyzed using the parameters fundame ntal frequency, jitter, and shimmer. For assessment of articulation, the formant-based voice area index of vocals and the length of the burst from apalatal stop consonant isused. For prosody, no characteristics were found that were applicable to the analysis of film archives. The results of age dependencies described by the phonetic categories are consistent with the assumptions and conclusions presented in the literature. This pilot project also confirms the possibility of creating valuable studies from publicly available sources., Roman Čmejla, Jarmila Behenská, Tereza Tykalová, Jan Rusz, and Literatura
