You're also going to look at the places where you don't have, "said," but some other verb instead: shouted, intoned, chirped, fluted, shrieked, purred, whispered, hissed, oiled, and on and on.
You got it. Most of those have to go. Especially the ones you like best. There is a place for verbs that tell how something was spoken, but it's a small place, and it only has room for a few words.
"Caroline," he said.
"Caroline," he whispered.
"Caroline!" he shouted.
Or maybe he has a cold. "Caroline," he croaked.
But for the most part, with some exceptions, you don't need fancy verbs to tell how something was spoken. You can use "said" a thousand times, without its being as noticeable as a habit of substituting other words. By the time your characters have chuckled, screeched, murmured, sneered, bellowed, and hissed their way through half a chapter, the writers will be wincing at every quote. You'll have a kind of written tic, distracting to the reader and impossible to ignore.
Now you have a lot more times when you've used "said." If you think there are too many, check to see if you've missed opportunities to show who's speaking in other ways.
You may not need to attribute the speech. If only two people are talking, quite a few speeches can be left unattributed, because it will be obvious from paragraphing and tone of voice who is speaking. Just don't leave out so many that the reader has to count back with his finger.
