extends our previous work on information bottleneck diarization
aiming to include large number of features besides MFCC
and TDOA while keeping computational costs low. At first
HMM/GMM and IB systems are compared in case of two and
four feature streams and analysis of errors is performed. Results
on a dataset of 17 meetings show that, in spite of comparable
oracle performances, the IB system is more robust to feature
weight variations. Then a sequential optimization is introduced
that further improves the speaker error by 5 {\^{a}}ˆ’ 8\% relative. In
the last part, computational issues are discussed. The proposed
approach is significantly faster and its complexity marginally
grows with the number of feature streams running in 0.75 real
time even with four streams achieving a speaker error equal to
6\%.}
