Bessel features for estimating number of speakers from multispeaker speech signals
Blekinge Institute of Technology, School of Engineering, Department of Electrical Engineering2011 (English)Conference paper (Refereed) Published
In this paper, we explore Bessel features to determine the number of speakers from multispeaker speech signals collected simultaneously from a pair of spatially separated microphones. The arrival of the speech signals from speaker to microphones gives the time delays of given speaker. The time delays can be estimated by performing the cross-correlation to the band limited multispeaker signals collected at the two microphones. Signals are band limited using a finite number of Bessel coefficients. The computer simulation results demonstrate the proposed method is efficient compared to existing methods.
