I was excited to see this. My results were not convincing.

- I used "create voice", and the page refused to allow me to create anything because the big green button at the bottom was disabled. Only 1 checkbox shows up out of the 3 labels, and I was unable to check even the box that was visible. I used console tools to remove the disabled property from the element and it worked. (I'm using Safari so maybe it doesn't work there properly)

- The generated voice did not sound like me (I used my own voice). It did have some familiar tones, but not really.

- I fiddled with top-p, temperature and voice guidance, but the improvement was minuscule.

- Also recording the voice did not work (did record, but couldn't replay it to verify). So I recorded it on my computer and uploaded a file and that did work.
