| Abstract: | Speech processing with microphone array can improve signal-to-noise ratio and can resolve the problem of performance decline of speech recognition caused by environmental noise,echo and reverberation.This paper introduces the rationales of speech enhancement systems of microphone array based on different structures including delay-sum(traditional beam method),adaptive beam and adaptive post-filtering,etc.The characteristics of various algorithms are summarised as well in this paper. |
