Prerecorded and AI Voice Robocalls: What the TCPA Prohibits

Prerecorded Voice Call Laws: The TCPA Rule Explained

The TCPA prohibits calls using an artificial or prerecorded voice to cell phones and home phone lines without prior express consent (47 U.S.C. 227(b)(1)), unless the call is an emergency or an FCC exemption applies. For sales calls, FCC rules require prior express written consent for both cell phones and home lines (47 CFR 64.1200(a)(2) and (a)(3)).

You do not need to prove that an autodialer was used. After the Supreme Court narrowed the definition of an autodialer in Facebook v. Duguid, recorded-voice claims became a more direct path in many robocall cases. The only technology question is whether a recording or a synthetic voice was used.

Are AI Voice Calls Legal? The FCC’s AI Voice Cloning Ruling

In early 2024, the FCC issued a Declaratory Ruling (FCC 24-17) confirming that the TCPA’s limits on artificial or prerecorded voices cover current AI technologies that imitate human speech or generate call content.

The ruling treats cloned voices as artificial because no real person is speaking. It also rejected the argument that conversational AI systems that act like live agents should be exempt. An AI that talks back to you is still an artificial voice.

The ruling built on the FCC’s earlier “soundboard” decision, which held that a live agent clicking through prerecorded clips does not change the fact that the call uses a prerecorded voice. The FCC applied the same reasoning to AI. The ruling also cited a Ninth Circuit decision describing artificial voices as including sounds generated by artificial intelligence (Trim v. Reward Zone USA).

Keep in mind that courts now decide for themselves how to read the TCPA rather than automatically deferring to the FCC. The AI ruling remains a strong persuasive authority, and the statute’s plain language points the same way.

Deepfake Robocall Case Study: The New Hampshire Biden Calls

Shortly before the 2024 New Hampshire primary, voters received robocalls featuring a cloned voice of President Biden that discouraged them from voting in the primary and instead told them their vote mattered in November. The FCC fined the political consultant behind the calls for caller ID spoofing violations under the Truth in Caller ID Act, and the carrier that passed the calls along with high-confidence caller ID attestation agreed to a separate penalty. The FCC noted that its AI ruling gives both federal regulators and state attorneys general tools to pursue callers like these.

Our news coverage of the New Hampshire voice cloning case follows what happened next, including the separate state criminal case, which ended in an acquittal. The case shows how an AI robocall can arrive: with a spoofed number and a familiar voice.

State Attorney General Robocall Enforcement

The TCPA also lets states sue. A state attorney general who believes a caller is engaged in a pattern or practice of unlawful calls to residents may seek an injunction and statutory damages for each violation, with more severe damages for willful or knowing conduct (47 U.S.C. § 227(g)). Before the AI ruling, a bipartisan group of state attorneys general urged the FCC to treat any AI-generated human voice as an artificial voice under the TCPA, and the FCC’s leadership said the ruling would help state AGs pursue the people behind these calls.

For you, this is a second route. If you cannot identify an AI caller well enough to sue, a detailed report to your state attorney general, with the voicemail attached, can support an investigation that reaches many victims at once.

Prerecorded Message Disclosure Requirements

Even a lawful recorded call must follow the FCC’s identification rules in 64.1200(b):

• At the start: clearly identify the business, person, or entity responsible for the call, using the business’s registered name.
• During or after the message, provide a callback number that is neither the autodialer’s number nor a 900 number.
• For sales messages: offer an automated voice or key-press opt-out shortly after the identification that adds you to the company’s do-not-call list and ends the call.
• If left on voicemail: include a toll-free number you can call later to reach that opt-out.

A recording that opens with something like “Hi, this is Sarah from the benefits department” and never names a company breaks the identification rule. One caution: courts disagree about whether you can sue directly over missing disclosures, and at least one state appellate court in Maryland has said the related statutory section does not create a private right of action. Missing disclosures are usually most useful as supporting evidence alongside a consent claim under 227(b), which does carry damages.

Exempt Prerecorded Calls: When Written Consent Isn’t Required

Some prerecorded calls to home lines are exempt from the written-consent rule, but only within limits (64.1200(a)(3)):

Calls beyond those caps, or any recording after you opt out, fall outside the exemption. Cell phones have a separate, narrower set of exemptions in 64.1200(a)(9) for free-to-the-consumer messages such as package delivery notices, bank fraud alerts, and certain health care reminders.

Abandoned Calls and Dead Air Robocalls

If a sales call connects and no one is there, the caller may have broken the abandoned-call rule. Telemarketers must quickly connect you to a live person after you answer, or play a recorded message naming the seller with an opt-out, and may abandon only a small percentage of answered calls in a campaign (64.1200(a)(7)). They must also let an unanswered call ring for a minimum duration before hanging up (64.1200(a)(6)).

Ringless Voicemail and the TCPA

Some marketers drop recorded messages straight into your voicemail without ringing the phone. The FCC has ruled that ringless voicemail counts as a call made with a prerecorded voice, so the consent and identification rules above apply. Our page on ringless voicemail lawsuits covers that practice.

How to Prove a Robocall Used a Recording or AI Voice

• Save the voicemail. It is the best evidence of a recorded message. Export it before your carrier deletes it.
• If you answer, note whether the voice paused unnaturally, repeated itself, ignored your questions, or responded off-topic.
• Write down any company name, website, or callback number the message gave.
• Screenshot the call log showing the date, time, and number.
• If the voice sounded like someone you know asking for money, hang up and call that person directly. Then report it to the FCC and your state attorney general.

Track each call in our robocall evidence log. Each unlawful recorded call is a separate violation, so the count matters. The damages page shows how the numbers add up.

What to Do About AI and Prerecorded Robocalls

If you never gave the company permission and the call played a recording or synthetic voice, you may have a claim for each call. Try to find out who is selling: press the option to speak to someone and ask for the company name, or note any website mentioned in the recording. Common sources of these calls include auto warranty robocalls and Medicare plan robocalls. Then read our guide on suing a telemarketer for the next steps.

Frequently Asked Questions About AI Robocalls

Are AI robocalls illegal?

AI-generated voice calls are legal only with the consent required by the TCPA. The FCC has ruled that AI and cloned voices are artificial voices, so callers need prior express consent, or written consent for sales calls, unless an emergency or exemption applies.

Is a soundboard call with a live agent a prerecorded call?

Yes, according to the FCC. A live agent selecting recorded clips does not change the fact that the call uses a prerecorded voice.

Do I need to prove an autodialer for a prerecorded call claim?

No. The TCPA’s ban on prerecorded and artificial voice calls applies regardless of how the number was dialed.

What must a legal prerecorded message include?

The caller’s identity at the start, a callback number, and for sales messages, an automated opt-out shortly after the identification. Voicemails must include a toll-free number to opt out.
