一种基于听觉特性的自适应小波语音增强方法
Method of adaptive wavelet speech enhancement based on auditory perception
摘要
Abstract
A method of adaptive wavelet speech enhancement based on human auditory perception is put forward.Noised speech signal is investigated using auditory perception wavelet transform.Auditory perception of signal of frequency and amplitude is maintained.The separated noise of signal by wavelet transforms is used as the input signal of adaptive filter.The optimal filtering method of signal-noise decomposition is realized by using RLS and correlated noise of removal signal.The simulation shows that the proposed method is excellent to realize the optimal estimate to the valuable signal and noise of the transient signal in the same frequency segment,enhancing the definition and understanding of the speech.关键词
