AI Recreates Voices of Deceased Pilots, Raising New Privacy Concerns
Artificial intelligence tools were used to reconstruct the voices of deceased pilots from cockpit recording spectrograms, prompting the NTSB to review public investigation records and raise concerns about privacy, ethics, and aviation data security.
The National Transportation Safety Board temporarily disabled access to its investigation docket system after discovering that AI-generated recreations of pilots’ voices from a fatal UPS cargo plane crash were circulating online.
Although federal law prevents the NTSB from releasing cockpit voice recorder audio, the investigation file for UPS Flight 2976 included a spectrogram—an image that visually represents sound frequencies. After Scott Manley noted that audio could potentially be reconstructed from the data, users reportedly combined the spectrogram with publicly available transcripts and AI tools to generate approximations of the cockpit recordings.
The incident raised concerns about how modern AI systems can reconstruct sensitive information from publicly available data, including the voices of individuals who died in accidents.
The NTSB restored access to its docket system on Friday but kept 42 investigations, including the UPS Flight 2976 case, temporarily closed while reviewing the records. The episode highlights growing privacy and ethical questions surrounding AI’s ability to recreate content from technical datasets that were never intended to reproduce original audio.
