摘要翻译：
提出了一种端到端的单通道非特定人多说话人语音分离方法，将时频（T-F）掩蔽、短时傅立叶变换(STFT)及其逆变换表示为深层网络中的层。以前的方法不是计算重构信号上的损失，而是使用基于目标STFT幅度的替代损失。这忽略了由相位不一致性引入的重建误差。在我们的方法中，损失函数直接定义在重构信号上，并对重构信号进行优化以获得最佳分离。此外，我们通过一个相位重建算法的展开迭代进行训练，该算法表示为一系列STFT和逆STFT层。虽然对于使用混合相位进行重建的方法，掩模值通常被限制在0和1之间，但如果估计的幅度与相位重建一起使用，这个限制就不太相关了。因此，我们为T-F掩蔽的输出层提出了几个新的激活函数，以允许掩蔽值超过1。在公开的wsj0-2mix数据集上，我们的方法实现了最先进的12.6dB尺度不变信号失真比（SI-SDR）和13.1dB SDR，揭示了基于深度学习的相位重构的新可能性，代表了解决众所周知的难以解决的鸡尾酒会问题的根本性进展。

英文摘要：
  This paper proposes an end-to-end approach for single-channel speaker-independent multi-speaker speech separation, where time-frequency (T-F) masking, the short-time Fourier transform (STFT), and its inverse are represented as layers within a deep network. Previous approaches, rather than computing a loss on the reconstructed signal, used a surrogate loss based on the target STFT magnitudes. This ignores reconstruction error introduced by phase inconsistency. In our approach, the loss function is directly defined on the reconstructed signals, which are optimized for best separation. In addition, we train through unfolded iterations of a phase reconstruction algorithm, represented as a series of STFT and inverse STFT layers. While mask values are typically limited to lie between zero and one for approaches using the mixture phase for reconstruction, this limitation is less relevant if the estimated magnitudes are to be used together with phase reconstruction. We thus propose several novel activation functions for the output layer of the T-F masking, to allow mask values beyond one. On the publicly-available wsj0-2mix dataset, our approach achieves state-of-the-art 12.6 dB scale-invariant signal-to-distortion ratio (SI-SDR) and 13.1 dB SDR, revealing new possibilities for deep learning based phase reconstruction and representing a fundamental progress towards solving the notoriously-hard cocktail party problem.
