This paper describes a system to identify people in broad-cast TV shows in a purely unsupervised manner. The system outputs the identity of people that appear, talk and can be identified by using information appearing in the show (in our case, text with person names). Three types of monomodal technologies are used: speech diarization, video diarization and text detection / named entity recognition. These tech-nologies are combined using a linear programming approach where some restrictions are imposed.
