Abstract
A beamforming device in the present invention includes a probability estimation unit, a steering vector unit, and a beamforming unit, wherein the probability estimation unit estimates a speech existence probability corresponding to a probability that a target speech signal exists based on an input vector; the steering vector unit provides an estimated steering vector according to the speech existence probability and an input vector; and the beamforming unit calculates a weight vector based on the speech existence probability, the input vector, and the estimated steering vector to provide an output vector, and the beamforming device of the present invention can more accurately extract the target speech signal from the input signal by estimating the speech existence probability corresponding to the probability that the target speech signal exists based on the input vector to provide the steering vector and the weight vector.
