NPR's David Greene reportedly sued Google LLC and Alphabet in Santa Clara County, alleging NotebookLM's Audio Overviews uses a synthetic male voice that purportedly mimics his cadence and delivery without consent or compensation. The complaint reportedly cited an independent voice-recognition analysis reporting 53–60% confidence his voice trained the model. Google reportedly called the allegations baseless and said the voice is based on a paid actor.
