1.Introduction

The Catalan Database for Mobile Telephone Network was recorded within the scope of a research project supported by the Catalonian Government. The design of the corpus and the collection was performed at the Universitat Politècnica de Catalunya (UPC). Transcription and formatting was performed at Verbio Speech Technologies, Spain.

The owner of the database is the Catalonian Government.
This database is an intermediate deliverable and comprises mobile (GSM) telephone recordings from 2000 speakers recorded directly over the fixed PSTN using two analogue lines. Signals were sampled at 8KHz and A-law encoded without automatic gain control. The database is distributed in 10 CD ROM volumes that contains the speech signals and one CD ROM volume that contains the documentation
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
TXT	DOS text file
SES	DOS text file
CAO	SAM label file, text file with ISO Latin 1 symbols
CAA	A- law speech signal file
PS	Postcript file

The DVD-ROM has the following directory structure:

\+-COPYRIGH.TXT

+-DISK.ID

The signal files are stored in 10 CD-ROM according to the ISO 9660 format. Label files and documentation files are stored in one CD-ROM
The list of the distribution disks and directories are contained in the README.TXT file, stored on each disk. Further details regarding the database contents, files and directories are provided in the documentation files in the DOC directory, the session and lexicon tables in the TABLE directory and contents files in the INDEX directory.
