经济实惠的自动实时字幕方法的承诺设想了这样一个未来：聋哑和听力障碍 (DHH) 用户只需拿起手机或其他移动设备即可立即获取周围世界的语音。虽然处理高度可变的自然语言的挑战阻碍了自动化方法足够可靠地完成这项任务，无法在教室或工作场所等环境中使用 [4]，但最近在众包方法方面的工作允许非专家字幕组为 DHH 用户提供类似灵活的字幕来源。这与当前的人力方法形成鲜明对比，当前的人力方法使用训练有素的专业字幕员，每分钟最多可输入 250 个单词 (WPM)，但每小时的成本也超过 100 美元。在本文中，我们描述了 Legion:Scribe（或简称“Scribe”）的实时演示，这是一种众包支持的字幕系统，允许未经训练的参与者和志愿者通过计算将他们的输入合并为一个集体答案，从而提供延迟不到 5 秒的可靠字幕，该答案比任何一个工作人员单独生成的结果更准确、更完整。
The promise of affordable, automatic approaches to real-time captioning imagines a future in which deaf and hard of hearing (DHH) users have immediate access to speech in the world around them my simply picking up their phone or other mobile device. While the challenges of processing highly variable natural language has prevented automated approaches from completing this task reliably enough for use in settings such as classrooms or workplaces [4], recent work in crowd-powered approaches have allowed groups of non-expert captionists to provide a similarly-flexible source of captions for DHH users. This is in contrast to current human-powered approaches, which use highly-trained professional captionists who can type up to 250 words per minute (WPM), but also can cost over $100/hr. In this paper, we describe a real-time demo of Legion:Scribe (or just "Scribe"), a crowd-powered captioning system that allows untrained participants and volunteers to provide reliable captions with less than 5 seconds of latency by computationally merging their input into a single collective answer that is more accurate and more complete than any one worker could have generated alone.
