Santa Clara County Superior Court Judge Shella Deen has overruled a motion by Google to dismiss a lawsuit filed by David Greene regarding AI voice usage. The case claims that Google misappropriated Greene's voice for features including its NotebookLM tool.
Why it matters
The ruling highlights the growing legal challenges tech companies face over the use of human voices in AI training and generation. By denying the demurrer, the court allows the case to move forward, addressing whether voice misappropriation constitutes a statutory right of publicity violation.
Google offers its NotebookLM tool as part of a $19.99-per-month Google One AI Premium subscription tier. The court's decision followed a forensic voice-recognition analysis that reportedly confirmed a match between an AI-generated voice and David Greene.
The players
David Greene
He is a radio journalist who hosted Morning Edition for 10 years and is the plaintiff in the lawsuit against Google.
It is a global technology corporation that offers AI-driven products including the NotebookLM platform.
Shella Deen
She is a Santa Clara County Superior Court judge who is presiding over the legal proceedings involving Google's AI voice usage.
The details
The lawsuit, which includes claims of unfair competition and unjust enrichment, stems from Google's use of a voice that forensic evidence identifies as Greene's. Judge Deen rejected Google's argument that the Copyright Act preempts these claims, noting the difficulty of distinguishing a journalist from their voice.

The Tech Race
This litigation arrives as the industry transitions toward generative voice technology, putting companies in direct conflict with traditional media professionals. It marks a departure from reliance on established copyright law, as plaintiffs increasingly turn to state-level right of publicity statutes to challenge AI-driven innovations.
The outcome of this case could determine how users interact with AI assistants and whether tech companies face stricter regulations for voice synthesis. If the case proceeds, it may lead to limitations on the voices available within consumer-facing AI products.
The takeaway
This case underscores the ongoing tension between rapid AI development and the protection of personal identity rights. Individuals concerned about their digital likeness should monitor state-level legal precedents that may set new standards for privacy in the era of generative models.
