Completely false. Even the journalists at the launch of "Sky" last year were singling it out of the batch of voices, and specifically asking OA about how it sounded like Johansson: https://www.washingtonpost.com/technology/2023/09/25/chatgpt...
In case it's not clear, my moderately low opinion of Open AI is bested only by my even lower opinion of journalists.
> The new personas for ChatGPT are named Sky, Ember, Breeze, Juniper and Cove. Each of the personas has a different tone and accent. “Sky” sounds somewhat similar to Scarlett Johansson, the actor who voiced the AI that Joaquin Phoenix’s character falls in love with in the movie “Her.” Deng, the OpenAI executive, said the voice personas were not meant to sound like any specific person.
The point is here is someone who 'actually listened to it' at the debut long ago, and immediately asked the OA people about it. I don't know what more you want for similarity. They launched several voices, without any of the mentions of Johansson or _Her_ that have been brought up here or the controversy, and back then and there, on the spot, people felt the need to ask about how one sounded 'somewhat similar' to Scarlett Johansson specifically.
