The BBN Mandarin broadcast news transcription system

Bing Xiang, Long Nguyen, Xuefeng Guo, Dongxin Xu

In this paper, we present the state-of-the-art BBN Mandarin Broadcast News (BN) transcription system that participated in the EARS Rich Transcription evaluations. As briefly mentioned in the literature before, the BBN 2003 evaluation system achieved 47% relative improvement compared to the baseline, a significant reduction in recognition errors. Since then the system performance has been improved by another 16%, mainly due to the additional acoustic training data selected via light supervision, automatically downloaded language training data, an enhanced phoneme set and a better algorithm for pitch extraction. The current system achieves 6.3% character error rate (CER) on the EARS 2003 and 2004 development test sets, running at four times real time (4√óRT).
