This paper describes the development of the CUHTK-Entropic 10xRT Broadcast News Transcription System. Previous HTK broadcast news transcription systems have focused on maximising accuracy with few constraints on compute power available. In order to develop a system running in under 10 times real time on a single CPU, detailed investigation and optimisation of the system architecture and mode of operation was required. This paper outlines those developments and discusses the way in which operation under 10xRT was ensured despite variability of the data to be recognised. On the 1998 test the system produced an average word error rate of 16.1% running in 9.5xRT.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
