内容总结：

美国国家运输安全委员会近日暂时关闭了其事故调查档案系统的公共访问权限，起因是一段利用AI技术合成的已故飞行员语音在网上传播。去年，一架UPS货运飞机在肯塔基州路易斯维尔失事，两名飞行员不幸遇难。有网民从该事故档案中的音频频谱图文件中提取数据，借助AI工具（如Codex）结合公开的飞行记录器文字稿，重建了驾驶舱语音记录。这种行为引发了伦理争议：联邦法律明确禁止将实际驾驶舱录音纳入公开档案，但频谱图文件却可能被技术手段还原为语音。委员会已于上周五恢复系统访问，但暂停了42项调查的公开查阅，包括涉事航班2976号的相关文件。

在人工智能热潮的最新迹象中，美国国家运输安全委员会发现去年联合包裹服务公司（UPS）一起坠机事故中遇难飞行员的声音被利用人工智能重建并在互联网上传播后，暂时撤回了对其案卷系统的访问权限。

联邦法律禁止美国国家运输安全委员会在案卷系统中收录驾驶舱录音，而该案卷系统原本包含大量调查数据，且历史上一直向公众开放。但这起事故的案卷中收录了一份语音记录仪的频谱图文件。频谱图通过数学处理将包括低频和高频在内的声音信号转化为图像。

热门YouTuber斯科特·曼利（其频道融合物理、天文学和电子游戏内容）在X平台上指出，有可能根据该图像中编码的兆字节数据重建音频。

而事实确实如此。据美国国家运输安全委员会称，人们利用这份频谱图以及公开的录音文字稿，重建了肯塔基州路易斯维尔市UPS 2976航班驾驶舱语音记录仪的近似音频。根据社交媒体上的帖子，他们使用了类似Codex的人工智能工具。

美国国家运输安全委员会于周五恢复了对案卷系统的公开访问权限，但保留了42项调查的封闭状态以待审查——其中包括与2976航班相关的调查。

In the latest sign of these AI-heavy times, the National Transportation Safety Board temporarily removed access to its docket system after discovering that voices of pilots who were killed in a UPS plane crash last year had been re-created using AI and were circulating on the internet.
The NTSB is prohibited by federal law from including cockpit audio recordings in its docket system, which otherwise contains troves of data on investigations and has historically been open to the public. But the accident docket for this flight included a spectrogram file of the voice recorder. A spectrogram uses a mathematical process to turn sound signals, including low and high frequencies, into an image.
Scott Manley, a popular YouTuber whose channel combines physics, astronomy, and video games, noted on X that it could be possible to reconstruct audio from the megabytes of data encoded in that image.
And that’s what happened. People took the spectrogram, along with the publicly available transcript, to create approximations of the cockpit voice recorder audio from UPS Flight 2976 in Louisville, Kentucky, according to the NTSB. They used AI tools like Codex, according to posts on social media.
The agency restored public access to the docket system on Friday but kept 42 investigations closed pending review — including the one related to Flight 2976.
