摘要：
In this paper, we propose adaptive wavelet threshold for noise cancellation. For this, we use threshold value which minimize Bayesian risk. And using entropy, we part the noisy signal into unvoiced signal section and the other signal section to apply each threshold value for each section. Experiment result shows that proposed algorithm is more efficient.
