What Is Cloned Voice Watermarking?
Cloned voice watermarking is a security technique that embeds a unique, often inaudible digital signal into AI-generated speech. This allows creators and companies to verify the origin of an audio file, ensuring that cloned voices are used responsibly and can be distinguished from real human recordings. As generative AI continues to evolve, these watermarks serve as a critical layer of defense against misinformation and unauthorized voice use, providing a digital paper trail for every word spoken by an AI.
