Broadcast news play an important role in our lives providing access to news, information and entertainment. The existence of subtitles is an important medium for inclusion of people with special needs and also an advantage on noisy and populated environments. In this work we will describe and evaluate a system for subtitling live broadcast news for RTP (Radio Televisao de Portugal) the Portuguese public broadcast company. Developing a fully automatic subtitling system is a huge breakthrough which results from the convergence of different research models and software developments to create a working system. Our online system has 12% word error rate for the displayed subtitles working under real time with an average latency of just 6.5 seconds.
