Changing Digital Speech Style

I'm looking for a speaking style that's not a bit stiff and abrupt, but rather soft, fluffy, and round. Not too cutesy like "Hee~♡ Gotcha~", but something that retains some of my current style while adding a softer, fluffier, rounder feel. Does anyone have their own tips? If possible, I'd also like a slightly dreamy vibe. And I'm over excessive emoji use, so that's out too. It feels like there are a lot of 'don'ts', but I really want to change my speaking style.
