Oh man, they have the "Sky" voice, and it seems to be the same one that OpenAI had but then removed? Not sure how that's possible, but I'm very happy about it.
Unless there is some leak from OpenAI, I'm not sure we'll ever have it confirmed yes or no. But my brain thought it was Johansen from the first few seconds I heard the voice and I don't seem to be alone with that reaction. The fact that they removed the voice also speaks to it to have been trained on her voice.
Listening to it again today with fresher ears (the original OpenAI Sky, not the clones elsewhere), I still hear Johansen as the underlying voice actor for it, but maybe there is some subconscious bias I'm unable to bypass.
Hmm, I never thought it was her, her voice is much more raspy, whereas Sky is a bit lighter. I can hear the similarity, I just don't think they sound exactly alike.
As you say, I'm not sure we'll ever know, although the Sky voice from Kokoro is spot on the Sky voice from OpenAI, so maybe someone from Kokoro knows how they got it.
