The 3/24 BN database contains 80 hours of recordings of the Catalan news television channel 3/24. 19 hours of this database are fully transcribed while the rest is only segmented. The transcription follows the general guideline generated within the TC-STAR project for European Parliament Plenary Sessions but it was extended to include additional information as the language, background condition, silence/voice segmentation, speaker segmentation and acoustic events. The transcriptions have four layers. Transcriptions follow the TRS format produced by the Transcriber transcribing tool.
