Bibliography 45 1.IntroductionThe Catalan Database for In-Car Applications was recorded within the scope of the ”Generació de recursos lingüístics per les technologies de la parla” project which was sponsored by the Catalan and Spanish Governments. Collection was performed at the Department of Signal Theory and Communications of the Universitat Politècnica de Catalunya (UPC) (Spain) and annotation was performed at Verbio Technologies. The owner of the database is the Catalan Government. This database comprises in-car recordings from 300 speakers recorded in 600 different sessions. The database follows the SpeechDat Car specifications (corpus content, speakers, transcription, lexicon, formats) and the Speecon specifications for the recording platform (speech signal formats and doc files). The database is distributed in 12 ISO 9660 DVD volumes and one CD ROM. The CD is used for text files and documentation, DVDs content recordings in the car. The content of each volume is described below. Tables show the disk identification name, the first and last codes of the sessions included in each disk and the effective number of sessions.
The list of the distribution disks and directories are contained in the README.TXT file. Further details regarding the database contents, files and directories are provided in the documentation files in the DOC directory and the files in the TABLE and INDEX directories. File types are identified with the following extensions: *.DOC - Microsoft Word V6.0 document *.LST - DOS text index file with ISO Latin 1 symbols *.TBL - DOS text file with ISO Latin 1 symbols *.SES - DOS text file *.TXT - DOS text file *.CAC - SAM label file, text file with ISO Latin 1 symbols for car recordings *.CA1 - Speech signal channel 1 *.CA2 - Speech signal channel 2 *.CA3 - Speech signal channel 3 *.CA4 - Speech signal channel 4 *.PS - Postcript file Each CD-ROM has the following directory structure: \: COPYRIGH.TXT - copyright notice DISK.ID - UNIX volume ID file README.TXT - readme file VEHIC2CA\ - data directory VEHIC2CA\DOC: DESIGN.DOC - Catalan database documentation file SUMMAR0.TXT - database contents summary file SAMPALEX.PS - SAMPA table ISO88591.PS - ISO 8859_1 table VEHIC2CA\INDEX: CONTENT0.LST - file/utterance/speaker index table VEHIC2CA\TABLE: LEXICON.TBL - full lexicon table REC_COND.TBL - Recording condition table SESSION.TBL - session table SPEAKER.TBL - speaker table VEHIC2CA\: - contains the data block directories BLOCK00\ - sessions are grouped in blocks BLOCK01\
