This paper describes the development of the Cambridge University RT-04 diarisation system, including details of the new segmentation and clustering components. The final system gives a diarisation error rate of 23.9% on the RT-04 evaluation data, a 34% relative improvement over the RT-03s evaluation system. A further reduction down to 18.1% is shown to be possible when using the segmentation algorithm alone.

which are gzip compressed, then you may be able to find

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.
