Abstract

Many speaker localization methods apply frequency smoothing to decorrelate the direct-path signal and coherent reflections. However, in practice, only modest decorrelation is accomplished, which may result in performance loss. In this paper, frequency smoothing weights for improved decorrelation are derived and shown to be inversely proportional to the source signal power at the specified frequency. An experimental study demonstrates the added performance when incorporating the proposed weights in a direct path dominance test-based speaker localization method.
