Thanks, @lukeharries! He explained that the issue was a bug: the voice wasn't working, and the slot for creating a new voice wasn't available either. They're going to fix it :) In the thread, I tried a lot of voice cloning services. In the end, I used: 1/ 11Labs, but the fast voice version. It's not perfect, but it can act pretty well. Can't wait to try the "professional voice" cloning. 2/ Minimax, also using the fast voice. It's super faithful to the original, but it can't really act. The others, like Resemblance, Fish, etc., were pretty meh. Sorry! I couldn't try Qwen because setting it up in Comfy is a whole mess, and I didn't have time.

So, like with pretty much every product, I went from 'this is a lame service' to 'ok, I'm using it now, I love you guys'. That's just how customers are :D I know because it happens to us at Magnific all the time too, hahahaha.
