George Carlin Estate Files Lawsuit Against Group Behind AI-Generated Stand-Up Special: ‘A Casual Theft of a Great American Artist’s Work’::George Carlin’s estate has filed a lawsuit against the creators behind an AI-generated comedy special featuring a recreation of the comedian’s voice.
I think your Madonna example is completely fine as long as they don’t call themselves Madonna and start uploading videos on YouTube with her name on it (like is the case here).
Madonna owns her name and trademark but not her tone of voice, style of songs or her wardrobe choices.
In the same way, The George Carlin estate doesn’t own his speech mannerism or comedic style but they certainly own his name.
