UNPOPULAR OPINION ALERT. TAKE THE TIME TO READ, IT COULD CHANGE YOUR LIFE (and it would be nice to get a debate going).
I think using "said" for most of your dialogue tags is extremely important. EXTREMELY. I'm really passionate about this, guys. XD
Using a bunch of words other than "said" makes the writing style feel forced and awkward. You really should be using "said" most often, and other words less often. Things like "replied" or "asked" are also fine, but not too much. The reason for this is that "said" is a filler word, like "the," that readers won't really process, and instead all their focus will be on what's more important, like the actual words the characters are saying, the body language they use, the setting, the atmosphere, etc etc. Reading something like "proclaimed," "uttered," "voiced," "quipped," "barked," WHATEVER, tends to jerk the reader out of the story. It forces them to focus on that word, which makes the reading experience rocky and pulls them out of your world, which is what you definitely don't want. I think if you're gonna describe the way someone is saying something, don't do it like this:
"Looks like the greenie messed up pretty bad again, huh fellas?" he sneered.
Do it like this: "Looks like the greenie messed up pretty bad again, huh fellas?" he said, turning to me with a pitying smile. It was humiliating.
Now the readers can focus on the atmosphere of what's going on. I feel like you have so much more room for describing HOW he said it without replacing "said" with another verb. "Sneered" could mean so many things, and I feel like it's overused. In the first line, was the bully's face angry? Gloating? Condescending? We don't really know. But in the second one, you know the exact way the bully is mocking him and exactly how it feels. It's sarcastic and humiliating. Readers will skip over "said," and then zero in on the body language. It makes for a more smooth reading experience, and won't pull them out of the story. You could even eliminate the "said" tag and just do: "Looks like the greenie messed up pretty bad again, huh fellas?" He turned to me with a pitying smile. It was humiliating.
It's okay to clarify when they're yelling, or crying, or whispering, or stuff like that of course, but when you could easily replace the word with "said," "asked," or "replied," do it.
