| Abstract(in English) | In this paper, we present an underdetermined speech enhancement method called the time-frequency-bin-wise switching beamformer. In this method, we switch multiple preconstructed beamformers in each time-frequency (TF) bin, each of which suppresses a particular interferer. However, this method requires the target-active period and interferer-wise-active periods as the prior information. In this paper, to overcome this limitation, we formulate the switching and construction of beamformers as a joint optimization problem, which can be understood from two viewpoints: the clustering of the most dominant interferer signal in each TF bin and the construction of MVDR beamformers using such bins. |
