Dialogue is one of the least teachable and most personal parts of writing. Writing dialogue is like writing music. It's extremely personal to you, but it should also have some sort of flow or "melody" about it, otherwise, it's not accomplishing its goal. You should speak your dialogue out loud and see if it flows (over and over). This is because it is meant to be said, not read and in your head, it does come across very different than if spoken. It doesn't necessarily have to be the way real people talk, it does, however, have to flow. How does the sound of dialogue (volume, speed, emphatic words) reinforce meaning, and what do they reveal about the character. Play the parts, talk out loud, perform the scene. This is how you keep your words from becoming stilted (even though, sometimes you ay be going for that in an uncomfortable/awkward scene).
You'll hear people say "that's not how people talk".. Who cares? people dont rhyme and Shakespeare never cared. If you can and that is your niche, that's fine but most of the time that happens through improve. But also you shouldnt make it how people talk on tv, (like Mike& Molly or something). add idiosyncracies, hiccups in the sentences, false starts to create the illusion of realism. even 2 characters speaking at the same time. You can have a conversation where more than one goal is accomplished. It can be a rollercoaster ride of discovery and mood changes.
