Approaches to Address AI-enabled Voice Cloning

Approaches to Address AI-enabled Voice Cloning

• Today, the FTC announced four winners of the Voice Cloning Challenge, which was launched to address the present and emerging harms of artificial intelligence, or “AI”-enabled voice cloning technologies.
• The FTC received submissions from a wide range of individuals, teams, and organizations.

Leveraging solutions to provide upstream prevention or authentication

• Prevention or authentication refers to techniques that limit the application and misuse of voice cloning software by unauthorized users.
• One commonly discussed approach for prevention and authentication is watermarking, which often refers to a “broad array of techniques” for embedding an identifying mark into a piece of media to track its origin to help prevent the misuse of cloned audio clips.
• [2] Invisible or visible watermarks can be altered or removed, potentially rendering them unhelpful for differentiating between real and synthetic content.

Applying solutions to detect solutions in real-time

Real-time detection or monitoring includes methods to detect cloned voices or the use of voice cloning technology at the time during which a specific event occurs. Studies reveal a spectrum of efficacy for voice cloning detection solutions.[5] The effectiveness of such solutions is especially important when considering the types of AI-enabled voice cloning scams – such as fraudulent extortion scams – that the technology can enable.

Using solutions to evaluate existing content

• The post-use evaluation of existing content includes methods to check if already-created audio clips such as voice mail messages and audio direct messages contain cloned voices.
• One potential way to evaluate existing audio clips is to develop algorithms that detect inconsistencies in voice cloned clips.

Looking forward: Preventing and deterring AI-enabled voice cloning scams and fraud

• While there are many exciting ideas with great potential, there’s still no silver bullet to prevent the harms posed by voice cloning.
• Further, voice service providers – telephone and VoIP companies – need to continue making progress against illegal calls.
• In addition, the Commission has recently enacted a new Impersonation Rule, which will give the agency additional tools to deter and halt deceptive voice cloning practices.
• There is no AI exemption from the laws on the books and the FTC remains committed to protecting consumers from the misuse of “AI”-enabled voice cloning technologies.
