A California judge has overruled a motion by Google to dismiss a lawsuit alleging the company misappropriated a voice for its AI products. The case centers on claims that Google used a radio host’s voice in its NotebookLM Audio Overviews feature without consent.
Why it matters
The ruling forces a legal challenge against a major tech company to proceed in state court, testing the limits of how AI firms can synthesize voices for generative tools. It highlights the growing tension between AI feature development and individual personality rights.
Google currently offers its Audio Overviews feature through a $19.99-per-month Google One AI Premium tier. Forensic analysis provided in the complaint points to a match between the plaintiff's voice and the synthetic audio.
The players
A global technology company that develops search, cloud, and generative AI platforms, including NotebookLM and the Google One subscription service.
Shella Deen
A Santa Clara County Superior Court judge presiding over the lawsuit regarding AI voice usage rights.
David Greene
A radio host who hosted Morning Edition and filed the lawsuit alleging his voice was misappropriated for synthetic audio.
The details
The lawsuit alleges Google used the host's voice in a December 2024 Spotify partnership and its broader NotebookLM platform. In overruling the demurrer—a formal request for a judge to dismiss a case for legal insufficiency—the court rejected the argument that the Copyright Act inherently preempts these claims because a voice is not copyrightable. The judge noted that distinguishing between a journalist's public persona and their specific vocal identity is complex, allowing the case to move toward discovery.
Timeline
September 2024: Google introduces NotebookLM Audio Overviews.
December 2024: The disputed voice is used in a Spotify partnership.
January 23, 2026: Lawsuit is filed against Google.
July 23, 2026: Case is remanded to state court.
October 23, 2026: Judge Shella Deen overrules Google's demurrer.
The Tech Race
The lawsuit highlights the ongoing legal uncertainty surrounding voice cloning, as federal progress on the NO FAKES Act remains stalled until the next congressional session. This case acts as a bellwether for how state courts will interpret publicity rights as AI voice synthesis becomes a standard feature in consumer productivity software.
The ruling marks the start of a litigation process that could influence how AI developers obtain voice licenses for consumer tools. Users of the $19.99-per-month Google One AI Premium tier may see changes to feature availability if the court mandates stricter consent requirements for synthetic voices.
The takeaway
This ruling establishes a hurdle for AI platforms, signaling that state-level right-of-publicity claims remain a viable avenue for individuals challenging AI voice synthesis. Watch for subsequent discovery filings in the Santa Clara County Superior Court that may reveal internal details regarding Google's voice-training datasets.
What happens next
No action on the federal NO FAKES Act is expected until the US Congress session resumes following the midterm elections.
