摘要

•Evaluation of baseline CHiME3 recogniser in diverse range of acoustic conditions.•Performance curves indicate relative influence of noise and reverberation.•Evaluation of 6 different speech enhancement pipelines.•Deverberation and beamforming dramatically improve performance in all conditions.•Improvement in STOI predicts improvement in WER.
