....when tested on its ability to detect whether or not one anchor person (Tom Brokaw) was talking. Our method di#ers from this approach in that we assume no prior knowledge of the acoustic characteristics of the di#erent speakers in the program. A number of researchers (Chen Gopalakrishnan 1998; Couvreur Boite 1999) have considered methods which cluster speaker segments into groups of acoustically similar segments. The goal of this work has usually been the adaptation of speech recognizers to different types of speakers or di#erent channel conditions. 2 We used the list of anchors journalists on the All ....
....to ours. The output of speech based systems contains no information about the types of di#erent speakers, although speaker identity would be very useful information in deriving speaker type, if it could be recovered with high accuracy. Unfortunately, speaker clustering is a di#cult task; (Couvreur Boite 1999) report 70 classification accuracy on broadcast news, even when the number of speakers is given a priori. Note that this classification accuracy may be quite su#cient for speech recognizer adaptation; in contrast, browsing tasks will usually require a lower error rate. Furthermore, this method ....
