Since I found the first website to generate digital voices, I always check if Italian voices are good enough. They weren't, they aren't, and they've never been.
They sound robotic OR with a strong English accent, which is even worse.
Not your fault, of course, but you didn't solve this.
Lorenzo, the first voice you propose if I switch to italian, sounds as someone from NYC.
What about all the other languages that I don't speak? They probably sound as weird as Italian.

Probably in the industry the budget for voice development is dedicated 99% to English voices and 1% to all the others.

Just what happened with Google Translate for years before AI came by:
- any language -> English: pretty good results
- English -> any other language: extremely low quality and weird/funny/unprofessional results.

My question: Will it ever change?
