Czech Broadcast News Transcripts contains the transcripts corresponding to the Czech broadcast news audio published as Czech Broadcast News Speech.
The audio recordings were collected from three Czech radio stations (Cesky rozhlas 1 Radiozurnal - CRo1, Cesky rozhlas 2 Praha - CRo2, Cesky rozhlas 3 Vltava - CRo3) and two TV channels (Ceska televize - CTV and Prima TV - Prima). The audio was recorded between February 1 and April 22, 2000, at the Department of Cybernetics, University of West Bohemia in Pilsen.
The corpus was created to support the development of large vocabulary speaker independent speech recognition systems for Czech.
There are 286 transcripts, corresponding to the 286 audio files (approximately 50 hours of broadcast news). The transcripts contain approximatelly 196K words and 27K unique words. The news does not contain weather forecasts, sports news, or traffic announcements. The stations, channels, number of files and number of hours are listed below:
The transcripts were created by native Czech speakers working at the Department of Cybernetics, University of West Bohemia in Pilsen, under the direction of Vlasta Radova. The transcription was done using software provided by the LDC (Transcriber 1.4.1). Those parts of the audio recordings that do not contain speech or where the signal was disrupted, were not transcribed. As a consequence, the corpus contains about 23 hours of transcribed speech. The transcriptions are provided both in the ISO-8859-2 and Windows-1250 character set.
