摘要:

语音增强和语音分离是两个相关的任务,其目的是分别从由几个源产生的声音的混合物中提取一个或多个目标语音信号。传统上,这些任务已经使用应用于可用声学信号的信号处理和机器学习技术来解决。由于语音的视觉方面基本上不受声学环境的影响,所以来自目标说话者的视觉信息,例如嘴唇运动和面部表情,也已经用于语音增强和语音分离系统。为了有效地融合声学和视觉信息,研究人员利用了数据驱动方法的灵活性,特别是深度学习,实现了强大的性能。大量用于提取特征和融合多模态信息的技术的不断提出突出了对全面描述和讨论基于深度学习的视听语音增强和分离的概述的需要。在本文中,我们对这一研究主题进行了系统的调查,重点关注文献中描述系统的主要元素:声学特征;视觉特征;深度学习方法;融合技术;训练目标和目标函数。此外,我们还回顾了基于深度学习的无声视频语音重建和非语音信号视听声源分离方法,因为这些方法或多或少可以直接应用于视听语音增强和分离。最后,我们调查了常用的视听语音数据集,因为它们在数据驱动方法和评估方法的开发中起着核心作用,因为它们通常用于比较不同的系统并确定其性能。

英文摘要:

Speech enhancement and speech separation are two related tasks, whose purpose is to extract either one or more target speech signals, respectively, from a mixture of sounds generated by several sources. Traditionally, these tasks have been tackled using signal processing and machine learning techniques applied to the available acoustic signals. Since the visual aspect of speech is essentially unaffected by the acoustic environment, visual information from the target speakers, such as lip movements and facial expressions, has also been used for speech enhancement and speech separation systems. In order to efficiently fuse acoustic and visual information, researchers have exploited the flexibility of data-driven approaches, specifically deep learning, achieving strong performance. The ceaseless proposal of a large number of techniques to extract features and fuse multimodal information has highlighted the need for an overview that comprehensively describes and discusses audio-visual speech enhancement and separation based on deep learning. In this paper, we provide a systematic survey of this research topic, focusing on the main elements that characterise the systems in the literature: acoustic features; visual features; deep learning methods; fusion techniques; training targets and objective functions. In addition, we review deep-learning-based methods for speech reconstruction from silent videos and audio-visual sound source separation for non-speech signals, since these methods can be more or less directly applied to audio-visual speech enhancement and separation. Finally, we survey commonly employed audio-visual speech datasets, given their central role in the development of data-driven approaches, and evaluation methods, because they are generally used to compare different systems and determine their performance.
