摘要翻译：
本文提出了话语级置换不变训练(uPIT)技术。uPIT是一个实用的、端到端的、基于深度学习的独立于说话人的多说话人语音分离解决方案。具体来说，uPIT将最近提出的置换不变训练(PIT)技术扩展为话语级代价函数，从而消除了帧级PIT在推理过程中需要解决的额外置换问题。我们使用递归神经网络（RNNs）来实现这一点，在训练过程中，最小化话语级分离误差，从而迫使属于同一说话人的分离帧与同一输出流对齐。在实践中，这使得RNNs在uPIT训练下，可以在没有任何信号持续时间、说话人数量、说话人身份或性别先验知识的情况下分离多说话人混合语音。我们在WSJ0和Danish两人和三人混合语音分离任务上评估了uPIT，发现uPIT优于基于非负矩阵分解(NMF)和计算听觉场景分析(CASA)的技术，并优于深度聚类(DPCL)和深度吸引子网络(DANet)。此外，我们发现用uPIT训练的模型可以很好地推广到未知的说话者和语言。最后，我们发现用uPIT训练的单个模型可以处理两个说话人和三个说话人的混合语音。

英文摘要：
  In this paper we propose the utterance-level Permutation Invariant Training (uPIT) technique. uPIT is a practically applicable, end-to-end, deep learning based solution for speaker independent multi-talker speech separation. Specifically, uPIT extends the recently proposed Permutation Invariant Training (PIT) technique with an utterance-level cost function, hence eliminating the need for solving an additional permutation problem during inference, which is otherwise required by frame-level PIT. We achieve this using Recurrent Neural Networks (RNNs) that, during training, minimize the utterance-level separation error, hence forcing separated frames belonging to the same speaker to be aligned to the same output stream. In practice, this allows RNNs, trained with uPIT, to separate multi-talker mixed speech without any prior knowledge of signal duration, number of speakers, speaker identity or gender. We evaluated uPIT on the WSJ0 and Danish two- and three-talker mixed-speech separation tasks and found that uPIT outperforms techniques based on Non-negative Matrix Factorization (NMF) and Computational Auditory Scene Analysis (CASA), and compares favorably with Deep Clustering (DPCL) and the Deep Attractor Network (DANet). Furthermore, we found that models trained with uPIT generalize well to unseen speakers and languages. Finally, we found that a single model, trained with uPIT, can handle both two-speaker, and three-speaker speech mixtures.
