For a “Hawking Edition” you would think it would sound at least close to him, but it doesn’t. First, It has a British accent which, although Dr. Hawking is from England, is incorrect because the computer program he used had an American accent. Second, the “robot sound” was completely wrong. It sounded like someone recorded the words and ran the voice through a program, which is not how Dr. Hawking’s sounded. My son was so disappointed. He wanted to actually sound like Dr. Hawking, who he was researching for school, for his famous person presentation. At least it was free.
