How could we implement a law that requires disclosure of an AI?

When I communicate via telephone or video, I would like to get an honest answer to the question "Are you human or an AI"? With GPT-3 and deepfakes improving, the day will soon be here when we are confronted with virtual humans indistinguishable from the real thing - at least to our senses. And when we ask them if They are human, they will lie and say yes. Is there a deep learning model that can distinguish between a human and an AI? TO put it another way - can a deep learning model be developed to perform a Turing test based on vocal cadence, diction, grammar, accent as well as visual cues (when dealing with an image)?
