Abstract (English)

This collaborative COST 25O action, in which almost all the European countries are involved, aims at studying the technological, economical and social feasibility of the use of automatic speaker recognition and speaker verification technologies in real life teleconi applications. This also involved the collection of the databases required for the development and evaluation of the algorithms. In 1998, as part of this COST 25O project, IDIAP and EPFL developed original algorithms and improved the decision threshold strategy. They also participated in the latest international NIST evaluation (National Institute of Standards and Technology, USA) and showed that their system was at the leading edge of speaker recognition technology. Among other developments, and in collaboration with the ELISA consortium, IDIAP implemented a fusion algorithm of different systems and showed that this strategy was actually yielding significant improvement of the speaker verification performance.
