摘要:

在过去的几年里,语音识别取得了巨大的进步。曾经被认为是极其困难的任务,如黑板,现在接近人类的表现水平。MALACH语料库(LDC目录LDC 2012 S 05)是由Shoah视觉历史基金会幸存者收集的大屠杀证词大型档案的375小时子集,对语音社区提出了重大挑战。该集合由不受约束的自然语音组成,其中充满了不流利、重口音、与年龄相关的协同发音、未提示的说话者和语言切换以及情感语音--所有这些对于语音识别系统来说仍然是悬而未决的问题。即使对于熟练的人类注释者来说,转录也是一个挑战。本文提出了社区的地方集中在MALACH语料库开发语音识别系统,更强大的口音,不流利和情绪化的讲话。为了降低进入门槛,我们创建了一个词典、培训和测试设置,并展示了使用当前深度学习技术的基线结果。元数据刚刚由LDC发布(LDC 2019 S11)。希望这一资源将使社区能够在这些基线的基础上建立起来,以便更广泛的受众能够获得这些和相关口述历史中极其重要的信息。

英文摘要:

There has been huge progress in speech recognition over the last several years. Tasks once thought extremely difficult, such as SWITCHBOARD, now approach levels of human performance. The MALACH corpus (LDC catalog LDC2012S05), a 375-Hour subset of a large archive of Holocaust testimonies collected by the Survivors of the Shoah Visual History Foundation, presents significant challenges to the speech community. The collection consists of unconstrained, natural speech filled with disfluencies, heavy accents, age-related coarticulations, un-cued speaker and language switching, and emotional speech - all still open problems for speech recognition systems. Transcription is challenging even for skilled human annotators. This paper proposes that the community place focus on the MALACH corpus to develop speech recognition systems that are more robust with respect to accents, disfluencies and emotional speech. To reduce the barrier for entry, a lexicon and training and testing setups have been created and baseline results using current deep learning technologies are presented. The metadata has just been released by LDC (LDC2019S11). It is hoped that this resource will enable the community to build on top of these baselines so that the extremely important information in these and related oral histories becomes accessible to a wider audience.
