Abstract

In this contribution, an acoustic front-end for distanttalking interfaces that only requires two microphone signals is presented. It comprises a directional blind source separation(BSS)-based noise and interference estimation scheme and Wiener-type filters for noise and interference suppression. The proposed front-end and its integration into a speech recognition system is analyzed and evaluated in noisy living-room-like environments representing a generalization of the PASCAL CHiME challenge, implying that the potential of the method is verified for a wide range of distances.
