They're definitely anime-style voices, though most of the female ones are very annoying. I couldn't stand to watch an anime with them.
They just sound like anime voices
Right, I’ve never seen an anime, probably for exactly this reason.
There are good ones without the stereotypical voices, I recommend Fullmetal Alchemist Brotherhood.
I bet you're talking about like English dubs. The original japanese voices are diverse. Aizen from Bleach, Hakshaku (Millennium Earl) from D. Grayman, Marshal D. Teach from One-piece, and All Might from my hero academia have deep regal voices.
