Broadcast news subtitling system in Portuguese

The subtitling of broadcast news programs are starting to become a very interesting application due to the technological advances in automatic speech recognition and associated technologies. However, to build this kind of systems, several advances are necessary both in terms of the technological components and on main blocks integration. In this paper, we are presenting the overall architecture of a subtitling system running daily at RTP (the Portuguese public broadcast company). The goal is to integrate our components in a system for the subtitling of RTP programs. The global system includes the subtitling of recorded and direct programs.
