Transcription of broadcast news with a time constraint: IBM’s 10xRT HUB4 system

We describe a system which automatically transcribes broadcast news in less than 10 times real-time. We detail the system architecture of this system, which was used by IBM in the 1999 HUB4 10xRT evaluation, and show that the performance of this system is over 20 percent more accurate at the same speed than the system we used in the 1998 evaluation. Furthermore, we have closed the gap in word recognition accuracy between an unlimited resource system and this which runs in under 10 times real time from 45 percent to 14 percent.
