If you write the way you'd take a B2 essay and try to deliver it out loud, you'll sound rehearsed and weirdly formal. Real spoken German is looser. It uses simpler tenses, drops words speakers can recover from context, and relies heavily on a small set of "thinking sounds" — words like also, ja, halt, ne, eigentlich, so. Most of these have no real meaning. They buy you a half-second to think, and they make you sound like a native.
Perfekt over Präteritum.
Outside of sein, haben and the modals, spoken German uses Perfekt for the past. "Ich habe gestern gearbeitet," never "Ich arbeitete gestern."
Shorter sentences.
Most spoken sentences are 1–2 clauses, not the 3–4-clause stacks you can get away with in writing. Verb-final structures still apply, but the structures are smaller.
Modal particles & fillers.
Words like halt, mal, doch, eben, ja, denn add tone but no propositional meaning. Knowing how to scatter them in is half the work of sounding native.
