Short answer

On February 8, 2024 the FCC ruled that calls made with AI-generated voices are 'artificial' under the Telephone Consumer Protection Act, so the same consent rules apply. The ruling gives enforcers more tools but does not stop scam calls from criminals who ignore the law. Treat any unexpected call as unverified, hang up and call back on a number you look up yourself.

Key takeaways

  • The FCC's unanimous declaratory ruling of February 8, 2024 recognises calls made with AI-generated voices as 'artificial' under the TCPA, effective immediately.
  • Telemarketers need prior express written consent before robocalling consumers, and the ruling applies that standard to AI voices.
  • The FCC said state attorneys general gain new tools, and a coalition of 26 of them backed the approach.
  • The FBI warned in May 2025 about text and AI-generated voice messages impersonating senior US officials to steal account access.
  • A law does not verify a caller. Hanging up and calling back on a number you find yourself remains the key defence.

What the FCC decided

On February 8, 2024 the Federal Communications Commission announced the unanimous adoption of a declaratory ruling that recognises calls made with AI-generated voices as “artificial” under the Telephone Consumer Protection Act (TCPA). The ruling took effect immediately. In the FCC’s words, it makes the voice-cloning technology used in common robocall scams illegal as a method, not only the fraud at the end of the call.

The FCC explained the background. The TCPA restricts autodialled calls and artificial or prerecorded voice messages, and under FCC rules telemarketers must obtain prior express written consent before robocalling consumers. The ruling holds AI-generated voices to those same standards. The announcement said bad actors use AI-generated voices in unsolicited robocalls to extort vulnerable family members, imitate celebrities and misinform voters.

The FCC also described who can act. It can fine robocallers and take steps to block calls from carriers that facilitate illegal robocalls. Individuals or organisations can sue under the TCPA, and State Attorneys General have their own tools tied to TCPA definitions. A coalition of 26 State Attorneys General wrote in support, and the FCC noted a Memorandum of Understanding with 48 of them to combat robocalls.

What the ruling does not do

The ruling changes the legal footing. It does not authenticate any call. A fraud ring that already breaks wire fraud and impersonation laws will not change course because of a TCPA ruling, and many operate outside US jurisdiction. The practical gain is more routes for enforcement and for pressuring carriers that pass traffic.

The UK regulator Ofcom shows a similar emphasis on the network side. Its scam calls page reports a fine of 437,500 pounds on the provider Tismi for failing to take appropriate and proportionate steps to stop its numbers being misused, including for scams, plus investigations into two more providers. For consumers, Ofcom’s advice is plain: avoid engaging, do not reply, click links or press buttons, and do not share personal or financial details.

Where AI voice calls show up

Three patterns appear in official warnings.

Family emergency calls. The FTC warned in March 2023 that scammers need only a short audio clip, perhaps from content posted online, plus a voice-cloning program to imitate a relative. The typical call is a panicked “grandchild” in jail or after a crash asking for money. See grandparent and family emergency scams and AI voice clone scams.

Official impersonation. The FBI’s May 15, 2025 alert said that since April 2025, malicious actors had impersonated senior US officials with text messages and AI-generated voice messages to build rapport, often sending a link under the pretext of moving to another messaging platform. The link can lead to a site that steals login credentials, which are then used to target the official’s contacts. Compare government impersonation scams.

Marketing and celebrity robocalls. The FCC specifically named celebrity imitation. The same trick fuels investment pitches, covered in deepfake celebrity investment ads.

How to handle a call that sounds real

The FBI says AI voice cloning “can sound nearly identical” to a real person, so sound quality is not a test. Its advice, which matches the FTC’s, is to verify independently.

  • Hang up. Look up the number of the organisation or person yourself and call back.
  • Check small details in numbers, email addresses and links that follow the call.
  • Never share a two-factor code with anyone who calls you, and keep two-factor authentication turned on.
  • Do not send money, gift cards or crypto on an unverified request.
  • Agree on a secret word or phrase with family, as both agencies recommend.

Protecting your own voice

The less audio of you that is public, the less material a cloner has. The FBI suggests limiting online sharing of images and voice and making social media accounts private. Practical steps are in how to protect your voice from cloning.

If you already acted on a call

Contact your bank immediately, change passwords on any account whose code or login you shared, and report to the FBI at ic3.gov or to the FTC at ReportFraud.ftc.gov. Tell the person who was supposedly calling, using a verified number, so their contacts can be warned.

What you can do

  1. 01Do not trust a voice on an unexpected call, even if it sounds like someone you know or a known organisation.
  2. 02Hang up and call the organisation or person back on a number you look up yourself, not one given in the call or message.
  3. 03Never share a verification code, gift card number, crypto or bank details on an inbound call.
  4. 04Agree a family safe word and use it before sending money to anyone who calls in distress.
  5. 05Report unwanted or scam calls to your carrier and to the FTC at ReportFraud.ftc.gov, and report losses to your bank.

Frequently asked questions

Are AI-generated voice robocalls illegal in the US?

The FCC ruled on February 8, 2024 that calls made with AI-generated voices are artificial under the TCPA. That means they face the same limits as other artificial or prerecorded voice calls, including prior express written consent for telemarketing. Scam calls were already illegal as fraud.

Does the ruling stop scammers from using voice cloning?

No. The FCC said the ruling gives state attorneys general new tools against the act of using AI voices in robocalls. Criminals who ignore consent rules, often from abroad, are not deterred by it, so personal verification still matters.

How can I tell if a call uses an AI voice?

You often cannot. The FBI suggests listening for unusual tone, word choice or call delays, but it also says AI voice cloning can sound nearly identical to the real person. Verify by calling back on a number you find yourself.

What if the caller says they are a family member in trouble?

The FTC advises not trusting the voice. Hang up and call the person at a number you already know, or contact another relative. Be wary of requests for wire transfers, crypto or gift cards, which are hard to reverse.
