	description = {Welcome to IEEE Xplore 2.0: Nonlinear filtering for speaker tracking in noisy and reverberantenvironments},
	abstract = {This paper addresses the problem of speaker tracking in a noisy
and reverberant environment using time delay of arrival (TDOA)
measurements at spatially distributed microphone pairs. The tracking
problem is posed within a state-space estimation framework, and models
are developed for the speaker motion and the likelihood of the speaker
location in the light of the TDOA measurements. The resulting
state-space model is nonlinear and nonGaussian, and consequently no
closed-form solutions exist for the filtering distributions required to
perform tracking. Here sequential Monte Carlo (SMC) methods are applied
to approximate the true filtering distribution with a set of samples.
The resulting tracking algorithm requires no triangulation, is
computationally efficient, and can straightforwardly be extended to
track multiple speakers},
