Some here said you need to use dialogue tags such as "barked" and "laughed" to show emotion or tone in the speaker's voice.
Someone on wattpad asked for alternatives to "said." Someone else offered the following link. I thought the article was good so I'm including it here.
There are 3 examples of the same dialogue in the article. The first one uses expressive verbs as dialogue tags. The second shows how to do it with action.
I actually don't like dialogue that has an action before every dialogue (the second example). I find that more distracting than "barked" and "laughed." I want to be immersed in the conversation.
But the third example, the one in "Numero Dos," is well done (IMHO).
