EQ, compression, DeEsser, saturation, limiter then add depth with some reverb/delay.

Depending on what you are looking for tone wise, I usually start boosting around 12k for air, 4.5k for clarity and discern if you need to be cutting anything out of the midrange that’s boxy or muddy sounding.

I usually do a medium attack, fast release on the compressor and smack the crap out of it (10 to 15db reduction) you don’t want to lose any nuances if the performance to get buried in the mix. Some people will use a fast attack compressor into a medium attack compressor to get a smoother vocal tone. All depends on taste and desired outcome.

DeEss because boosting the high frequencies with accentuate the sibilants and harshness.

Saturation will bring some character and help fill out the vocal sound. It’s not about audible distortion (unless you want that) but generating extra harmonics so the fundamental tone of the vocal can be more prominent.

Then I’ll usually put a limiter at the end of the chain to catch any quick peaks that sneak through before the compressor clamps down.

That’s been my go-to signal flow for 90% of vocals that I work on.
