Abstract
In this paper we introduce the quantitative and qualitative characteristics of the Czech Radio Broadcasts News during a period of significant political and social changes in the Czech Republic (1969-2005). The research is mainly focused on the quantitative features of speech that can be determined from the results of automatic speech recognition system.
We describe selected characteristics on the level of language and speech of the Radio Broadcasts News; namely the changes in studio vs. out-of-studio speech ratio, distribution of speakers by male and female, moderators and guest-speakers, approximate use of phrasal introductory and closing language specific for the time periods, speech speed changes, average silence length, coordinative vs. subordinate conjunctions ratio and the most frequent semantic words.
