Analysis of CFA-BF: Novel combined fixed/adaptive beamforming for robust speech recognition in real car environments

Abstract

Among a number of studies which have investigated various speech enhancement and processing schemes for in-vehicle speech systems, the delay-and-sum beamforming (DASB) and adaptive beamforming are two typical methods that both have their advantages and disadvantages. In this paper, we propose a novel combined fixed/adaptive beamforming solution (CFA-BF… (More)
