Corpus NetDC d'actualités radio-diffusées arabes
The NetDC Arabic BNSC (Broadcast News Speech Corpus) is a corpus developed by ELDA in the framework of the European-funded project Network of Data Centres (NetDC). The project was done in collaboration with the LDC (Linguistic Data Consortium), which has produced a similar corpus from the news broadcasted by Voice of America Arabic in the United States. The database contains ca. 22.5 hours of broadcast news speech recorded from Radio Orient (France) during a 3-month period between November 2001 and January 2002 (37 broadcast news, including 32 from the 5.55 pm news and 5 from the 10.55 pm news). The language is Standard Arabic from the Middle East region. The database is stored on 1 DVD-ROM. The database was validated by SPEX, the Netherlands, to assess its compliance with NetDC specifications.
Recordings were made through a Sangean ATS 909 radio receiver connected to a desktop PC. Encoding is 16 kHz, 16 bits, single channel. Format is raw PCM (.wav) with header information.
The corpus was segmented, labelled and transcribed manually using the “Transcriber” software, developed by DGA (Délégation Générale pour l'Armement, France) and LDC (Linguistic Data Consortium, USA) (with an additional patch for Arabic). The transcriptions were done in Arabic characters and the software automatically generated the transliterations. Transcriptions include speaker turns, topics, channel information.
Each speech file (extension .wav) has an accompanying ASCII SAM label file with recording information (extension .sam), and an accompanying file with the transcription in xml format (extension .trs) and channel information. A phonetic lexicon in Arabic SAMPA has also been included.
