Comunicació presentada a: IV Jornadas en Tecnología del Habla, celebrat del 8 al 10 de novembre de 2006 a Saragossa. ; In this paper we present a person identification system based on a combination of acoustic features and 2D face images. We address the modality integration issue on the example of a smart room environment. In order to improve the results of the individual modalities, the audio and video classifiers are integrated after a set of normalization and fusion techniques. First we introduce the monomodal acoustic and video identification approaches and then we present the use of combined input speech and face images for person identification. The various sensory modalities, speech and faces, are processed both individually and jointly. The result obtained in the CLEAR'06 Evaluation Campaign shows that the performance of the multimodal approach results in improved performance in the identification of the participants. ; This work has been partially sponsored by the EC-funded project CHIL (IST-2002 − 506909) and by the Spanish Government-funded project ACESCA (TIN2005 −08852).
