NPR Host David Greene Sues Google Over Alleged Voice Resemblance in NotebookLM

Google’s NotebookLM has quickly become one of the most talked-about AI productivity tools on the market. Designed to turn documents into summaries, study guides, and even full podcast-style audio conversations, the feature that arguably stands out most is its AI-generated voice narration. However, that same voice narration may have just put Google into some legal trouble.

David Greene sues Google over NotebookLM’s voice

According to a report by The Washington Post, longtime NPR host David Greene is suing Google, claiming that the male AI podcast voice in NotebookLM closely mirrors his own (via TechCrunch). Greene, who previously hosted NPR’s “Morning Edition” and now leads “Left, Right, & Center” on KCRW, says friends, family, and colleagues began pointing out the resemblance shortly after the tool became famous.

He reportedly became convinced that the AI voice was copying his cadence, tone, and even subtle filler words like “uh.” “My voice is, like, the most important part of who I am,” Greene told the publication, highlighting the personal and professional value of vocal identity for broadcasters.

Google denies allegations

Google, however, has denied the allegation. A company spokesperson told The Washington Post that the NotebookLM voice is based on a paid professional actor and is not connected to Greene in any way. This isn’t the first time AI-generated voices have sparked controversy. Last year, OpenAI removed a ChatGPT voice after actress Scarlett Johansson raised concerns that it sounded too similar to her.

As AI voice tools grow more realistic, disputes like this may become more common, raising fresh questions about where inspiration ends and imitation begins.
