       abstract = {This work describes a novel system for speaker
diarization of meetings recordings based on the combination of acoustic
features (MFCC) and Time Delay of Arrivals (TDOA). The first part
of the paper analyzes differences between MFCC and TDOA features
which possess completely different statistical properties. When Gaussian
Mixture Models are used, experiments reveal that the diarization system
is sensitive to the different recording scenarios (i.e. meeting rooms with
varying number of microphones). In the second part, a new multistream
diarization system is proposed extending previous work on Information
Theoretic diarization. Both speaker clustering and speaker realignment
steps are discussed; in contrary to current systems, the proposed method
avoids to perform the feature combination averaging log-likelihood
scores. Experiments on meetings data reveal that the proposed approach
outperforms the GMM based system when the recording is done with
varying number of microphones.},
