I've listened to it, and it sounds nothing like Scarlett does. I had to find a movie with Scarlett in it to compare with, and I can honestly tell you ChatGPT sounds nothing like Natasha in Black Widow.
(Joke aside, ChatGPT doesn't sound like Scarlett at all).
I probably should say "IMO".
They played it on a local radio station here yesterday, and even they were mocking it as "not close".
