Particle Filtering Beamforming for Acoustic Source Localization in a Reveberant Environment

Williamson, Robert; Ward, Darren B


Traditional acoustic source localization uses a two-step procedure requiring intermediate time-delay estimates from pairs of microphones. An alternative single-step approach is proposed in this paper in which particle filtering is used to estimate the source location through steered beamforming. This scheme is especially attractive in speech enhancement applications, where the localization estimates are typically used to steer a beamformer at a later stage. Simulation results show that the...[Show more]
