Czech Broadcast News Speech contains audio recordings 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 audio files, totaling approximately 50 hours of broadcast news. The news does not contain weather forecasts, sports news, or traffic announcements. The audio files are single-channel, 22.05 kHz, 16 bit linear wav files. The stations, channels, number of files and number of hours are listed below:
The corresponding transcripts are available as Czech Broadcast News Transcripts. 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 in both the ISO-8859-2 and Windows-1250 character set.
Please listen to this audio sample.
The completion of this corpus was facilitated by funding provided by the Ministry of Education of the Czech Republic (Grants No. MSM235200004 and LN00A063) and by the National Science Foundation (NSF) project no. IIS-9820687 entitled "1999 Language Engineering Workshop for Students and Professionals: Integrating Research and Education (WS99)" under the agreement no. 8004-48231 between the Johns Hopkins University, Baltimore, Maryland, and the University of West Bohemia in Pilsen, Czech Republic.
