DATABASES FOR SPEAKER RECOGNITION: ACTIVITIES IN COST250 WORKING GROUP 2

Abstract

Working Group (WG) 2 of the COST250 Action "Speaker Recognition in Telephony" has dealt with databases for speaker recognition. The present paper gives an overview of the activities in this WG, and presents its main results. The first result is an overview of 36 existing databases that has been used in speaker recognition research. Those include both public and proprietary databases. As part of the overview, some of the variability represented in those databases is analyzed. The second result is the publicly available Polycost database, a telephony-speech multisession database with 134 speakers from all around Europe. Together with pre-defined experiment specifications, this database is a useful resource to aid in the assessment of speaker recognition systems in general, and in comparing systems across sites, in particular.
