- W2368761915 abstract "A novel method was proposed for speech enhancement based on unscented particle filter(UPF) and subband decomposition.First of all,the noisy speech is decomposed into subband speech signals.And then these signals are modeled as low-order time-varying autoregressive(TVAR) processes.Secondly,unscented particle filters are applied to estimate the parameters and process the subband speech signals.Finally,the enhanced fullband speech signals are reconstructed from the enhanced subband speech signals.Simulation results show that the proposed method can improve obviously signal-to-noise ratio and the quality of speech,and it is easily realized on real time." @default.
