Detecting deep-fake audio through vocal tract reconstruction is an epic scientific work, against fake human-like voices, from the w:University of Florida in published to peers in August 2022.

The Office of Naval Research (ONR) at of the USA funded this breakthrough science.

The work Who Are You (I Really Wanna Know)? Detecting Audio DeepFakes Through Vocal Tract Reconstruction at, presentation page, version included in the proceedings[1] and slides from researchers of the Florida Institute for Cybersecurity Research (FICS) at in the w:University of Florida received funding from the w:Office of Naval Research and was presented on 2022-08-11 at the 31st w:USENIX Security Symposium.

This work was done by PhD student Logan Blue, Kevin Warren, Hadi Abdullah, Cassidy Gibson, Luis Vargas, Jessica O’Dell, Kevin Butler and Professor Patrick Traynor.

The University of Florida Research Foundation Inc has filed for and received an US patent titled 'Detecting deep-fake audio through vocal tract reconstruction' registration number US20220036904A1 (link to with 20 claims. The patent application was published on Thursday 2022-02-03. The patent application was approved on 2023-07-04 and has an adjusted expiration date of 2041-12-29.

“This is brilliant new science from the University of Florida against the human-like voice-thieving systems in 2022! 👏🏻 👏🏻 👏🏻

Thank you to the University of Florida and their Florida Institute for Cybersecurity Research (FICS) and very warm thank you to the respective scientists for this ground-breaking science against the voice-thieving systems. May ☮️ be with you.

This looks like an awesome start on future automated armor for us humans against the voice-thieving systems!

These methods based on extremely innovative application of existing scientific knowledge and realizing to ask the right questions and the system the University of Florida researchers made to spot the fake synthesized voices and how this system was designed, implemented, tested and found highly effective against the voice-thieving machines of today gives us hope in humanity's struggle to stay humanity despite of the menaces of the synthetic human-like fakes.

This was an issue needing solving, as the digital sound-alikes / audio "deepfakes" / audio "deep fakes" / voice-thieving synthesis systems are known to have been used for crimes since March 2019. Office of Naval Research funding was a natural source of funding for this innovation, as it is clear that protecting the US Navy and US Marines audio communications networks against any voice-forging adversaries is of high importance.

People who were aware of the voice-thieving-machines problem had been waiting for something and this is more than at least I expected. 🥳 🥳

Cheers American taxpayers and DoD for funding this breakthrough science!

Please get this technology against the fake voices to humans to protect the humans and humanity! 🫵🏻”
