California AB 2905 updates the state’s rules for automatic dialing-announcing devices, the systems behind prerecorded robocalls. Callers using prerecorded messages must first make a live announcement, and that announcement must now disclose if the prerecorded message uses an artificial voice.

How California AB 2905 Defines an Artificial Voice

An artificial voice under this law is one generated or significantly altered using artificial intelligence. That definition captures cloned voices, fully synthetic voices, and AI-modified recordings, so the disclosure duty attaches to most modern voice AI used in outbound calling.

Compliance Stakes

Noncompliance violates Public Utilities Commission requirements and carries criminal exposure, which puts this well beyond a routine regulatory checkbox. Any business running outbound call campaigns with AI-cloned or synthetic voices into California must add this disclosure to the live announcement that precedes the message. Marketing teams should audit their call scripts and dialer configurations to confirm the disclosure is actually delivered on every call.
