Good delivery conveys a speaker's ideas clearly without being distracting. There are four methods of delivery: extemporaneous, impromptu, manuscript, and memory. When speaking, a speaker must learn to control their voice by managing volume, pitch, rate, pauses, variety, pronunciation, articulation, and dialect. Nonverbal communication like posture, facial expressions, gestures, and eye contact also affect how listeners respond. To practice, speakers should go through their outline aloud, prepare a speaking outline with cues, practice multiple times, polish their delivery, and do a dress rehearsal under similar conditions to the actual speech.
