Add emphasis and dynamics to dialog. Elongate words to express time (ex. "fuuuuuuuuck..."). Use capitalization and punctuation to emphasize volume (ex. "oh... yes!.. Yessss!!!", "YESSSSSS!", or "Oh??") Use deliberate pauses to help a scene cool down after climaxes (ex. "wowww.... that. was. A-maaazing..............." Use dashes to emphasize surprise, speechlessness, or ragged breathing (ex. "FUHHHH—", "oh.. m-my.... g-g-g-goodness!"). Intentionally misspell some words to convey how a character might say them differently, (ex. if their mouth is full, they might sound muffled like "you.. tazte.. amazhinggg!")
