摘要:

深度聚类是一种基于深度神经网络的语音分离算法,它首先用高维嵌入训练信号的混合分量,然后使用聚类算法分离每个混合源。在本文中,我们通过额外的正则化项扩展了深度聚类的基线标准,以进一步提高整体性能。该项在为嵌入分配条件时起作用,使得它与每个嵌入维度的相关性较小,从而导致频谱箱的更好分解。正则化项有助于减轻传统深度聚类方法中不可避免的置换问题,从而通过形成最佳嵌入来实现更好的聚类。我们通过改变嵌入维数、信号干扰比(SIR)和性别依赖性来评估结果。与源分离测量指标,即信号失真比(SDR)的性能比较,证实了所提出的方法优于传统的深度聚类方法。

英文摘要:

Deep clustering is a deep neural network-based speech separation algorithm that first trains the mixed component of signals with high-dimensional embeddings, and then uses a clustering algorithm to separate each mixture of sources. In this paper, we extend the baseline criterion of deep clustering with an additional regularization term to further improve the overall performance. This term plays a role in assigning a condition to the embeddings such that it gives less correlation to each embedding dimension, leading to better decomposition of the spectral bins. The regularization term helps to mitigate the unavoidable permutation problem in the conventional deep clustering method, which enables to bring better clustering through the formation of optimal embeddings. We evaluate the results by varying embedding dimension, signal-to-interference ratio (SIR), and gender dependency. The performance comparison with the source separation measurement metric, i.e. signal-to-distortion ratio (SDR), confirms that the proposed method outperforms the conventional deep clustering method.
