2019年FEARLESS STEPS（FS-1）挑战赛是激励语音和语言社区进行精简和协作努力的第一步，旨在解决大量自然主义音频，这是同类中的第一个。Fearless Steps Corpus收集了超过19，000小时的多通道录音，这些录音是在多种噪音条件下来自450多个扬声器的自发语音。大多数阿波罗任务的原始模拟数据是未标记的，到目前为止，已经推动了无监督和半监督策略的发展。这一版本的挑战鼓励开发核心语音和语言技术系统，用于有限的地面实况/低资源可用性的数据，并旨在作为从如此庞大的未标记语料库中提取高级信息的“第一步”。与挑战赛一起，CRSS-UTDallas还向公众发布了11，000小时的同步30通道阿波罗-11音频数据。在本文中，我们描述了无畏的步骤语料库，挑战任务，其相关的基线系统，和结果。最后，我们还提供了CRSS-UTDallas团队在首届Fearless Steps Challenge期间获得的见解。
The 2019 FEARLESS STEPS (FS-1) Challenge is an initial step to motivate a streamlined and collaborative effort from the speech and language community towards addressing massive naturalistic audio, the first of its kind. The Fearless Steps Corpus is a collection of 19,000 hours of multi-channel recordings of spontaneous speech from over 450 speakers under multiple noise conditions. A majority of the Apollo Missions original analog data is unlabeled and has thus far motivated the development of both unsupervised and semi-supervised strategies. This edition of the challenge encourages the development of core speech and language technology systems for data with limited ground-truth/low resource availability and is intended to serve as the “First Step” towards extracting high-level information from such massive unlabeled corpora. In conjunction with the Challenge, 11,000 hours of synchronized 30-channel Apollo-11 audio data has also been released to the public by CRSS-UTDallas. We describe in this paper the Fearless Steps Corpus, Challenge Tasks, their associated baseline systems, and results. In conclusion, we also provide insights gained by the CRSS-UTDallas team during the inaugural Fearless Steps Challenge.
