Short answer: In the US, the FCC ruled in February 2024 that AI-generated voices count as "artificial" voices under the Telephone Consumer Protection Act, so robocalls using them need the same prior consent as other robocalls. California separately makes it unlawful to use an online bot to mislead people about being a bot in order to sell something or sway a vote, unless it discloses that it is a bot. How these apply to one particular call depends on the facts, so check with a lawyer.
FCC, February 8, 2024: AI-generated voices fall under the TCPA's rules for artificial or prerecorded voices.
The TCPA can be enforced by the FCC, by state attorneys general and by individuals in court.
California's bot law covers online bots used to mislead for a sale or a vote; clear disclosure avoids liability.

The FCC's 2024 ruling on AI voices
The Telephone Consumer Protection Act (TCPA) is the main US law on robocalls. It restricts calls that use an "artificial or prerecorded voice". In a Declaratory Ruling announced on February 8, 2024, the FCC confirmed that those words cover today's AI technologies that generate human voices, including voice cloning. The ruling took effect straight away.
What that means in practice: a call that uses an AI-generated voice is treated like any other artificial-voice call under the TCPA. Calls of that kind to mobiles and home lines generally need the called person's prior express consent unless an exemption applies, and the FCC's announcement notes that telemarketing robocalls need prior express written consent. The ruling also says the TCPA's identification and opt-out requirements apply to AI calls.
The FCC said the change gives state attorneys general new tools against robocallers. The TCPA already let the FCC fine robocallers and let people and organisations sue.
California's bot disclosure law
California Business and Professions Code § 17941, added by SB 1001 in 2018 and in force since July 1, 2019, makes it unlawful to use a bot to communicate with a person in California online with the intent to mislead them about its artificial identity, in order to encourage a purchase or sale or to influence a vote. A person using a bot is not liable if they disclose, clearly and conspicuously, that it is a bot.
The law defines a bot as an automated online account, and it is written for online interactions. How it applies to a voice call is not spelled out in the text, which is one reason to take advice for your own case. California lawmakers have also proposed updates, such as AB 410 in the 2025–2026 session; check its current status before relying on the old text alone.
What responsible AI callers do
Separate from what the law requires, the larger consumer products set their own rules, and they point the same way. Google's help page says Gemini's Call for me opens each call by saying it is an AI assistant from Google, that the line is recorded, and who it is calling for. xAI asks Grok Bot users to accept calling terms that limit calls to US businesses and people who have agreed to hear from them.
| Question to ask | Why it matters |
|---|---|
| Who is being called: a home line, a mobile or a business landline? | The rules differ, and mobiles include many small businesses' listed numbers. |
| Is it one call for one person, or many calls? | Campaigns and telemarketing carry the strictest consent rules. |
| Is the call recorded? | Recording consent rules differ between states and countries. |
| Does the caller say it is an AI if asked? | Misleading people about being a bot is what disclosure laws target. |
Key terms in plain English
- Robocall: in everyday use, a call made with an automated system or an artificial or prerecorded voice.
- Artificial or prerecorded voice: the TCPA's words. Since the 2024 ruling, the FCC reads them to include AI-generated voices.
- Prior express consent: permission given before the call. The FCC notes that telemarketing robocalls need it in writing.
- Declaratory Ruling: an FCC decision that explains how an existing law applies, rather than writing a new one.
- Bot (California): an automated online account whose actions or posts are all or almost all not made by a person.
Two practical points follow. First, the FCC ruling is about the voice: an AI voice puts a call under the TCPA's artificial-voice rules, so a call that needed no consent with a live caller may need consent with an AI voice. Second, California's law targets deception for a sale or a vote, and clear disclosure is its safe harbour. Neither is a complete list of the rules that may apply to you.
Outside the US
Canada, the UK, Australia and the EU each have their own rules on automated calls, recording and AI transparency. We have not summarised them here because the details vary and change. Check the regulator for your country.
Using a consumer AI caller for your own errand is different from running a calling campaign. If you are planning many calls, or calls to people rather than businesses, take advice before you start.
If you are on the receiving end
If an AI voice calls you with a sales pitch you did not agree to, you can report it. In the US, the FCC takes complaints about unwanted calls. For blocking them in the first place, see how AI call screening works.
Questions people ask
Is it illegal for an AI to call me?
Not in itself. In the US, robocalls using an AI voice face the same TCPA rules as other artificial-voice calls, including prior consent for calls to mobiles and home lines unless an exemption applies.
Does an AI caller have to say it is an AI?
It depends on where you are and what the call is for. California's bot law covers online bots used to mislead for a sale or vote. Ask a lawyer about your situation.
When did the FCC rule on AI voices?
The FCC announced its Declaratory Ruling on February 8, 2024, and it took effect immediately.
