Vijay Balasubramaniyan is the CEO and co-founder of Pindrop. He first joined me on the podcast way back in 2019 for episode 86. I still recommend people listen to that episode. You will learn a lot about voice authentication. In 2021, Vijay returned for episode 193. We now have him three years later and the topic is new.   Deepfakes and voice clones are common topics of discussion now, but Pindrop has been working on this for more than seven years. As a leading voice authentication solution, the team was intent to understand how voice clones could be used to impersonate a trusted user. Fast forward to 2023 and 2024 and they have a commercial product called Pindrop Pulse for deepfake detection.   It is state of the art deepfake detection that is already being used by several large financial institutions. Results from customers deployed in 2023 show a 99% identification rate for voice clones created by the leading synthetic voice providers, 90% for zero-day voice clones from unknown providers, and both metrics come with a sub-1% false positive rate. These stats are essential as you will see lots of claims, but most are identifying a small subset of voice clone types or carry an impractically high false positive rate.
