The Macquarie Speaker Diarisation System for RT04S
Steve Cassidy · 2004
The primary purpose of the Macquarie participation in RT04s was to establish a baseline diarisation system bringing together recent work done in our group. As such, the performance of the system was not expected to be competitive, but rather to help highlight the issues in the diarisation task where we could usefully concentrate our efforts. The system combined a simple speech/silence decision, delta BIC speaker segmentation and single Gaussian speaker models to perform the diarisation task. Hierarchical clustering was used to derive between 3 and 10 speaker clusters; models based on each number of speakers were then compared using a BIC corrected likelihood measure on the data. 1.
