In this paper we shall describe key improvements to Dragonís Broadcast News Transcription System, which include: the addition" of a "speaker-change detection al-gorithm to" our preprocessing subsystem, a new diagonalizing transformation trained using semitied co-variances, "and the addition of probabilities on pronunciations. "This new transcription system yields a word error" rate of 15.2% on the 1997 evaluation test data, and 14.5%" on the 1998 evaluation test data.
