摘要: 給出了一種基于小波變換的漢語語音信號預處理的方法。通過小波變換中的Mallat算法來分解漢語語音信號,能夠消除信號冗余度,提高數據壓縮比,而不影響語音信號的真實效果。同時還給出了小波變換原理和Mallat算法以及實驗結果。Abstract: The Mallat's Algorithm in wavelet transforms is used to preprocess the chinese speech signal. By decomposing the speech signal, the compression ratios is improved under the certain distortion degree. The theory of wavelet transforms and the Mallat's Algorithm are proposed and the method is verified by the experimental results.
