Play a scene, as you open your mouth to say something, pause, and say something else. It helps to open your mouth wide before you say your line. Verbal Two players alternate sentences to build a scene. Verbal Characters must alternate lines of only one word each. Gestures and facial expressions are almost necessary.
Sound effects work, too.
Unlike One Word at a Time, players speak one word at a time forming continuous sentences and telling a story together. Try to keep the flow and speak with one voice. Be in the moment. It is dangerous to try to plan ahead. Say the first thing that makes sense.
