TL;DR

David Greene, longtime host of NPR’s “Morning Edition,” is suing Google over claims that the male podcast voice in NotebookLM is based on his voice. Google denies the claim, saying the voice comes from a paid professional actor.

The Lawsuit

David Greene, who hosted NPR’s “Morning Edition” for years and currently presents KCRW’s “Left, Right, & Center,” has filed a lawsuit against Google. He alleges that the male AI voice used in Google’s NotebookLM podcast feature replicates his cadence, intonation, and characteristic use of filler words like “uh.”

Greene said friends, family members, and coworkers began contacting him about the resemblance, which ultimately convinced him to take legal action. “My voice is, like, the most important part of who I am,” Greene told The Washington Post.

NotebookLM, Google’s AI research assistant, includes a feature that generates podcast-style audio summaries with AI hosts. A Google spokesperson disputed Greene’s claims, telling the Post: “The sound of the male voice in NotebookLM’s Audio Overviews is based on a paid professional actor Google hired.”

A Growing Pattern

The lawsuit adds to a growing list of disputes over AI systems that appear to replicate real people’s voices. The most high-profile case involved actress Scarlett Johansson, who objected to an OpenAI ChatGPT voice she said sounded like an imitation of her. OpenAI subsequently removed the voice.

These cases sit at the intersection of intellectual property law and AI development, where the legal framework is still catching up with the technology. Voice actors, musicians, and broadcasters have increasingly raised concerns about AI systems trained on their work without consent or compensation.

Looking Forward

The outcome of Greene’s case could set a meaningful precedent for voice rights in the age of AI-generated audio. As AI podcast and voice products become more common, the question of what constitutes a protected vocal identity — and how close is too close — will need clearer legal answers.
