| 摘 要： | 提出一种有效解决不相互独立语音源信号混合的分离算法.利用子带分解方法,将混合信号分解成多个子带信号,在各个子带上分别进行语音分离得出语音分离信号,利用提出的相关性能指数,判断出相互独立的子带信号,把该子带的分离矩阵作为混合信号的解混合矩阵对混合信号进行分离.实验证明了本算法对相关语音源信号较好的分离效果.

| Abstract: | This paper presents a new algorithm for speech separation in which the speech source signals can be dependent.Mixed signals are decomposed to subband signals by subband decomposition.Speech separation signals can be gained by using speech separation in each subband.The subband signals which are mutually independent can be estimated by the correlation performance index proposed in this paper.The demixing matrices in the above subband are used as demixing matrices of original mixing speech signal.By computer ... |
