FCC Issues Notice of Proposed Rulemaking Regarding the Use of AI-Generated Technologies for Consumer Communications
The Federal Communications Commission (FCC) recently issued a unanimous Notice of Proposed Rulemaking and Notice of Inquiry targeting the use of AI-related technologies for communicating with consumers.1 In the proposed rule, the FCC seeks to impose a broad definition for AI technologies subject to the requirements of the Telephone Consumer Protection Act (TCPA). Companies using technology falling within the FCC’s proposed definition would be required to make certain disclosures under the TCPA to notify consumers that they are communicating with AI-technology. This proposal is the latest move by the FCC to tackle its largest source of consumer complaints: unwanted and illegal robocalls and robotexts.2 The proposed new rule may require companies to modify their current approach in engaging with consumers through AI-generated calls and/or texts, including potentially altering their current practices in collecting consent where necessary.

FCC Rules AI-Generated Voices Are “Artificial” Under the TCPA
The Federal Communications Commission (FCC) recently declared that AI-generated voices do fall within the meaning of “artificial” under the Telephone Consumer Protection Act (TCPA) in a ruling issued on February 8, 2024.1 The ruling follows a recent surge in robocalling and robotexting using AI technologies that simulate a human voice or that generate call content using a prerecorded voice, resulting in a significant number of complaints from consumers and attorneys general. Going forward, businesses and callers who use AI-generated voices will need to ensure they first obtain, at a minimum, prior express consent from the receiving party and otherwise comply with the requirements of the TCPA.
