摘要:

手语是丰富的多通道语言,需要以精确,复杂的方式表达手动(手)和非手动(面部和身体)特征。手语生成(SLP)是从口语到手语的自动翻译,必须体现这种完整的手语形态才能被聋人社区真正理解。以前的工作主要集中在手动功能的生产,与下阐述的输出所造成的回归的平均值。在本文中,我们提出了一个对抗性的多通道方法SLP。我们将符号生产视为基于变压器的生成器和条件判别器之间的极大极小博弈。我们的对抗性测试评估了以源文本为条件的符号生产的现实主义,将生成器推向现实和清晰的输出。此外,我们完全封装的标志发音包括非手动功能,生产面部特征和口型模式。我们对具有挑战性的RWTH-PHOENIX-Weather-2014 T(PHOENIX 14 T)数据集进行了评估,并报告了用于手动生产的最先进的SLP回译性能。我们为多通道标志的生产设定了新的基准,以支持未来对现实SLP的研究。

英文摘要:

Sign Languages are rich multi-channel languages, requiring articulation of both manual (hands) and non-manual (face and body) features in a precise, intricate manner. Sign Language Production (SLP), the automatic translation from spoken to sign languages, must embody this full sign morphology to be truly understandable by the Deaf community. Previous work has mainly focused on manual feature production, with an under-articulated output caused by regression to the mean. In this paper, we propose an Adversarial Multi-Channel approach to SLP. We frame sign production as a minimax game between a transformer-based Generator and a conditional Discriminator. Our adversarial discriminator evaluates the realism of sign production conditioned on the source text, pushing the generator towards a realistic and articulate output. Additionally, we fully encapsulate sign articulators with the inclusion of non-manual features, producing facial features and mouthing patterns. We evaluate on the challenging RWTH-PHOENIX-Weather-2014T (PHOENIX14T) dataset, and report state-of-the art SLP back-translation performance for manual production. We set new benchmarks for the production of multi-channel sign to underpin future research into realistic SLP.
