Abstract
The Czech Radio archive of spoken documents is considered one of the gems of the Czech cultural heritage. It contains the largest collection (more than 100.000 hours) of spoken documents recorded during the last 90 years. We are developing a complex platform that should automatically transcribe a significant portion of the archive, index it and eventually prepare it for full-text search. The four-year project supported by the Czech Ministry of culture is challenging in the way that it copes with huge volumes of data, with historical as well as contemporary language, a rather low signal quality in case of old recordings, and also with documents spoken not only in Czech but also in Slovak. The technology used includes speech, speaker and language recognition modules, speaker and channel adaptation components, tools for data indexation and retrieval, and a web interface that allows for public access to the archive. Recently, a demo version of the platform is available for testing and searching in some 10.000 hours of already processed data.
