Hi Dloux,
welcome to the Apple (user-to-user) Community!
Re: Unable to create personal voice
Seems you need a Mac with Apple Silicon (ie: not Intel) to create a personal voice.
and you must also have a login password set.
(Also: Personal Voice may not be available in some languages).
Re: Apple Silicon: If in doubt, Apple Support provides this info. (from article below):
"To see whether your Mac has an Apple silicon chip,
choose Apple menu > About This Mac.
If a chip is listed — for example, Chip Apple M1 —
then your Mac has an Apple silicon chip."

If all above is ok, and you haven't already:
Try restarting your Mac (ie: Apple menu > Restart)
(Deletes temporary files, re-establishes connections, may update recent setting changes, and often restores order if something is not working as expected.)
Then check to see if you can create the personal voice.

If you still can't create the personal voice, and you haven't already:
With a browser open / accessible for the download:
You might want to try following the steps in Apple support's MacOS 15 article:
