THC's VoiceVantage Blocks Top Five Deepfake Voice Products

In 533 independent university tests, THC Technologies' Voice Vantage software successfully blocked deepfake attempts using all five leading voice cloning solutions. Using True Identities, 178 deep-faked veriphrases were attempted during Phase 1 and 240 deep fake attempts using fake identities were attempted in Phase 2.

Phase 1 showed only a single authentication attempt across 178 attempts at a passing score of 60 meaning that only one of the 178 deep faked veriphrases were able to pass as a genuine user, at a rate of 0.56%.In all cases, a passing score of 60 but below a score of 79-89 would result in a Help Desk Referral.

In total, using False Identities, 240 deepfaked veriphrases and recorded authentication attempts were carried out across all attack scenarios, verification methods, users, veriphrases, and deepfake applications in Phase 2. In the internal attacker situation tests, six of the 120 total tests resulted in a verification using a deepfaked voice passing score of 60, a rate of 5 percent. The external attacks, on the other hand, saw four verifications, again at a passing score of 60 using deepfaked voices across 120 tests, a rate of 3.33 percent. In all cases, a passing score of 60 but below a score of 79-89 would result in a Help Desk Referral.

"User-friendly deepfake tools allow anyone to clone a voice from just a few seconds of recorded audio and are now publicly available online. Five of the most popular tools: FakeYou, ResembleAI, ElevenLabs, PlayHT, and Descript, make the creation of deep fake voices available to the average user," said Frances Lynch, CEO of THC Technologies, in a statement.
