There is a computer program that can generate human-like conversations with a deceased person's voice. - Apparently.
In 2019, the company Deepcake released an AI-powered system that can take a person's voice and merge it with their likeness in a video. The system uses machine learning algorithms to create a convincing conversation with the deceased person. The technology was first demonstrated with a video of the Soviet cosmonaut Alexei Leonov, who had passed away in 2019. The video was created using a 30-minute conversation recorded with Leonov in 2017, which was then used to train the AI model.
