The REPERE Challenge aims to support research on people recognition in multimodal conditions. To assess the technology progress, annual evaluation campaigns will be organized from 2012 to 2014. In this context, the REPERE corpus, a French video corpus with multimodal annotation, has been developed. The systems which participated in the dry run had to answer the following questions: Who is speaking? Who is present in the video? What names are cited? What names are displayed? The first results obtained during a dry run show that significant progress are quite possible. The challenge is to combine the various information coming from the speech and the images.
