IBM ’ s 10 x Real-time Broadcast News Transcription System Used in the 1999 Hub 4 Evaluation
We describe the system used by IBM in the 1999 HUB4 Evaluation under the 10 times real-time constraint. We detail the s ystem architecture and show that the performance of this system is over 20 percent more accurate at the same speed than the system used i n th 1998 Evaluation. Furthermore, we have closed the gap betwee n our unlimited resource system and our 10 times real time system f ro 45 percent to 14 percent.
