REPORT renals:rr07-46/IDIAP Recognition and Understanding of Meetings The AMI and AMIDA Projects Renals, Steve Hain, Thomas Bourlard, Hervé EXTERNAL http://publications.idiap.ch/attachments/reports/2007/renals-idiap-rr-07-46.pdf PUBLIC Idiap-RR-46-2007 2007 IDIAP The AMI and AMIDA projects are concerned with the recognition and interpretation of multiparty meetings. Within these projects we have: developed an infrastructure for recording meetings using multiple microphones and cameras; released a 100 hour annotated corpus of meetings; developed techniques for the recognition and interpretation of meetings based primarily on speech recognition and computer vision; and developed an evaluation framework at both component and system levels. In this paper we present an overview of these projects, with an emphasis on speech recognition and content extraction.
