Concluding Remarks on Multi-band and Multi-stream Research for Noise-Robust ASR

This paper summarizes our work carried out over the last four years on multi-band and multi-stream processing as means to achieve robust automatic speech recognition (ASR). Main focused is laid on the "full combination" approach which integrates over all possible positions of reliable data, instead of combining the nominal subbands or streams only. The main combination rules are summarized and the final results from a wide range of experiments are presented.
