| 摘 要： | 探讨具有延迟的欠定语音盲分离问题,针对语音信号的部分W-分离正交性,提出一种新的基于混叠矩阵估计的语音盲分离方法.首先对观测信号进行短时傅里叶变换,选定一个信号作为参考信号,构造幅度衰减向量和时间延迟向量,提取单源主导区间的观测信号作为观测样本;然后对观测样本进行聚类,通过估计参考信号的混叠系数来估计混叠矩阵;最后结合...

| Abstract: | The problem of underdetermined blind speech separation for delayed source signals is studied in this paper.A new blind speech separation method based on mixing matrix estimation is proposed for the partial W-disjoint orthogonality of speech signals.First,the short-time Fourier transform is used to process the observed signals,and the amplitude attenuation vectors and time delay vectors are constructed based on the selected reference signal,and the observed signals are extracted in the single-source dominate... |
