The advances in the digital era have led to rapid dissemination of information. This has also aggravated the spread of misinformation and disinformation. This has potentially serious consequences, such as civil unrest. While fact-checking aims to combat this, manual fact-checking is cumbersome and not scalable. While automated fact-checking approaches exist, they do not operate in real-time and do not always account for spread of misinformation through different modalities. This is particularly important as proactive fact-checking on live streams in real-time can help people be informed of false narratives and prevent catastrophic consequences that may cause civil unrest. This is particularly relevant with the rapid dissemination of information through video on social media platforms or other streams like political rallies and debates. Hence, in this work we develop a platform named \name{}, that can aid in fact-checking live audio streams in real-time. \name{} has a user-friendly interface that displays the claims detected along with their veracity and evidence for live streams with associated speakers for claims from respective segments. The app can be accessed at http://livefc.factiverse.ai and a screen recording of the demo can be found at https://bit.ly/3WVAoIw.

翻译：数字时代的进步促进了信息的快速传播，同时也加剧了错误信息和虚假信息的扩散。这可能带来严重的潜在后果，例如社会动荡。尽管事实核查旨在应对这一问题，但人工事实核查过程繁琐且难以规模化。虽然目前存在自动化事实核查方法，但这些方法无法实时运行，且往往未能充分考虑错误信息通过不同模态传播的特性。这一点尤为重要，因为对实时流媒体内容进行主动事实核查，能够帮助公众及时识别虚假叙述，从而避免可能引发社会动荡的灾难性后果。随着社交媒体平台上的视频内容以及政治集会和辩论等流媒体形式的信息快速传播，这一需求显得尤为迫切。为此，本研究开发了一个名为 \name{} 的平台，旨在辅助对实时音频流进行事实核查。\name{} 提供用户友好的界面，可实时显示检测到的主张及其真实性判定与证据，并关联各音频片段对应的发言者。该应用可通过 http://livefc.factiverse.ai 访问，演示视频可于 https://bit.ly/3WVAoIw 查看。
