The BABEL Database is a speech database that was produced by a research consortium funded by the European Union under the COPERNICUS programme (COPERNICUS Project 1304). The project began in March 1995 and was completed in December 1998. The objective was to create a database of languages of Central and Eastern Europe in parallel to the EUROM1 databases produced by the SAM Project (funded by the ESPRIT programme). The BABEL consortium included six partners from Central and Eastern Europe (who had the major responsibility of planning and carrying out the recording and labelling) and six from Western Europe (whose role was mainly to advise and in some cases to act as host to BABEL researchers). The five databases collected within the project concern the Bulgarian, Estonian, Hungarian, Polish, and Romanian languages. The Estonian database consists of the basic "common" set which is: - Many Talker Set: 30 males, 30 females; each to read 50 numbers, 1-2 connected passages, 1 block of "filler" sentences, and 1 block of syllables. - Few Talker Set: 4 males, 4 females; each to read 50 numbers, 10 connected passages, 1 block of "filler" sentences, and 2-3 blocks of syllables. - Very Few Talker Set: 1 male, 1 female; each to read 2 blocks of 50 numbers, 40 connected passages, 4 blocks of "filler" sentences, and 9 blocks of syllables. And the extension part: a short description of Estonian sound system.
