据悉，目前主流的内容安全审核方法是AI+人工审查，这是一种“事后审查”的处理方式。而虎牙开发的这套系统是一种先审后发的技术，基于虎牙自研的音频算法以及多媒体加工平台leaf，可以在不增加直播延时的条件下，对直播过程中的违规音频进行实时消音，有效降低甚至完全阻断风险内容的传播，实现实时屏蔽、先审后发。“针对AI能力在内容风控上的场景应用，我们优先选择了人工审核难度高、效率慢的直播音频场景上进行应用，下一步，我们将在直播视频场景中做出尝试。”虎牙风控团队负责人表示。 为了在直播场景内做到无延时，虎牙多巴胺AI技术团队对语音识别模型以及解码模块进行了大量优化，对每个语音片段的解码能够达到稳定一致的识别时间。“这很重要，因为音频片段解码时间的大幅波动，会导致违规音频漏出。在普通的2.1G主频CPU上，我们的实时率达到0.08，相当于1s音频只需要80ms就能识别出来”，虎牙AI消音技术负责人表示。 直播场景的复杂性较一般的语音识别场景要大，而复杂场景的识别准确率一直是业界难点。“准确率低会造成直播的大面积误消音，使用户的体验感降低，召回率低会导致漏出违规语音，为了得到高召回、高准确率的目标，虎牙多巴胺团队开发了基于直播场景的VAD算法、语音识别算法、后处理算法，同时收集了大量复杂场景的样本，进行算法迭代优化，使得我们在直播这种复杂场景下，也有较高的识别准确率以及召回率。另一方面，AI模型的优化仍然依赖样本校准工作，这是大量的、系统性、长期且细致的。”上述负责人表示。 国家互联网信息办公室部署开展2022年“清朗”系列专项行动时指出，此次行动重点针对网络直播、信息内容乱象、网络谣言、未成年网络环境等10个方面。对每一家互联网内容平台来说，确保平台内容的合法性和规范性，健全平台内容审核机制成为必须重视的问题。 资料显示，虎牙于2015年开始研发的“天眼”AI引擎，将人工智能、计算机视觉等前沿技术成果与互联网内容安全相结合。该系统可针对不同场景赋能AI能力，实现智能识别(包含音视频、图像、文本)和业务风控的落地创新，让传统的内容安全工作更高效、更节省成本，并实现自动化风险预判。此外，“虎牙天眼内容安全SaaS解决方案”目前已于亚马逊云上线，实现了对网络视听行业的赋能。 虎牙直播内容风控负责人表示，平台一直深入推进内容安全保障工作，采用“AI智能识别、人工审核和网络志愿者”三位一体模式。天眼实时消音系统是平台AI安全应用的一次扩容，平台将打造全方位安全攻防和更精准的内容审核体系，为健康的网络直播内容生态建设提供参考样本和前沿解决方案。（文章来源：中国新闻网）","news_type":1},"isVote":1,"tweetType":1,"viewCount":1049,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"CN","totalScore":0}],"lives":[]}
