The archive covers 90 years of public broadcasting and contains hundreds of thousands audio documents. The developed modular platform employs our LVCSR system that has to cope with 2 related languages: Czech and Slovak. Furthermore, it must deal with audio files of varying quality (e.g. recordings originally stored on matrices or tapes, data passed through analog and digital telephone lines, speech recorded during parliament or court sessions, etc.) The system includes speaker and language identification modules, a narrow-band signal detector, a music/song detector, and several other components to enhance transcription accuracy and provide support for multi-optional search. We evaluate the performance on broadcast news test sets grouped according to decades. We show that afte
