Hoover Launches AI Transcription of Nixon Tapes
The Hoover Institution's Applied History Working Group will transcribe and annotate more than 3,000 hours of recordings from the Nixon White House.
Updated on Nov. 8, 2026 in Artificial Intelligence
The Hoover Institution's Applied History Working Group announced a project to transcribe and annotate the Nixon White House tapes, which comprise more than 3,000 hours of audio maintained by the National Archives and Records Administration. Luke A. Nichter will lead the work using AI-assisted audio processing with hand verification.
Why it matters
No complete, standardized, and rigorously verified transcription of the full collection has previously existed, so the project aims to make the recordings searchable and reliable for researchers. The initiative reports a sustained accuracy rate of 98 percent on clean audio, with every transcript checked against NARA's official finding aids.
The project reports 98 percent sustained accuracy on clean audio across a collection of more than 3,000 hours recorded from February 1971 to July 1973. Accuracy on degraded or noisy recordings has not been reported.
The players
Hoover Institution
Hoover Institution is a public policy research center at Stanford University in Stanford, California, known for its historical archives and scholarship.
Luke A. Nichter
Luke A. Nichter is a historian who spent about 20 years transcribing manually and now leads the Nixon tape project using AI-assisted methods.
National Archives and Records Administration
The National Archives and Records Administration is the U.S. federal agency responsible for preserving government records, including the Nixon White House tapes.
The details
Nichter developed a method that combines AI-assisted audio processing with hand verification against the original recordings, cross-referencing each transcript for speaker attribution and historical context. The recordings were made secretly in the Oval Office, Cabinet Room, Camp David, Executive Office Building, and Lincoln Sitting Room.
Timeline
February 1971: Secret Nixon tape recordings begin.
July 1973: Secret Nixon tape recordings end.
November 7, 2026: Transcription initiative is announced.
Big Picture
The project builds on the National Archives and Records Administration's long-standing custody of the Nixon White House tapes, adding a searchable transcription layer to a collection that has never had a complete, verified text version. It shows how AI-assisted methods can be paired with hand verification to process large government audio archives.
Researchers and the public will gain access to a searchable, verified text of the Nixon tapes instead of relying on fragmentary or unverified transcripts. The project also indicates how archival audio collections may become easier to study as similar AI-assisted methods are adopted.
The takeaway
Large audio archives can become useful to researchers once AI-assisted transcription is paired with careful human verification against official records. The Nixon project shows that this combination can make a long-inaccessible collection searchable and reliable.
