摘要:

在真实世界场景中收集的语音数据通常会遇到两个问题。首先,多个源可能同时存在,并且源的数量可能随时间而变化。其次,录音中背景噪声的存在是不可避免的。为了处理第一个问题,我们参考语音分离方法,该方法将语音从未知数量的说话者中分离出来。为了解决第二个问题,我们参考了语音去噪方法,该方法去除噪声分量并检索纯语音信号。已经提出了许多基于深度学习的语音分离和去噪方法,这些方法显示出有希望的结果。然而,很少有作品试图同时解决这些问题,尽管语音分离和去噪任务具有相似的性质。在这项研究中,我们提出了一个联合语音分离和去噪框架的基础上的多任务学习标准,同时解决这两个问题。实验结果表明,该框架不仅在语音分离和去噪任务上表现良好,而且在大多数情况下优于相关方法。

英文摘要:

Speech data collected in real-world scenarios often encounters two issues. First, multiple sources may exist simultaneously, and the number of sources may vary with time. Second, the existence of background noise in recording is inevitable. To handle the first issue, we refer to speech separation approaches, that separate speech from an unknown number of speakers. To address the second issue, we refer to speech denoising approaches, which remove noise components and retrieve pure speech signals. Numerous deep learning based methods for speech separation and denoising have been proposed that show promising results. However, few works attempt to address the issues simultaneously, despite speech separation and denoising tasks having similar nature. In this study, we propose a joint speech separation and denoising framework based on the multitask learning criterion to tackle the two issues simultaneously. The experimental results show that the proposed framework not only performs well on both speech separation and denoising tasks, but also outperforms related methods in most conditions.
