Rehearse the presentation aloud, practicing eye contact, pace, volume, and timing using note cards rather than a read-aloud script.
Good delivery has a few concrete, practicable parts: eye contact with the audience instead of the notes, a pace slow enough to follow but not dragging, a volume that reaches the back of the room, and appropriate pauses instead of filler words like "um."
Rehearsal is what turns key-phrase notes into confident, natural speech. Practicing aloud multiple times -- and timing yourself -- builds the comfort that makes a presentation feel like talking, not reading.
Mastery looks like: They rehearse aloud from note cards with steady eye contact, appropriate pace and volume, and pauses instead of filler words.
Common stumbles: Reading straight down at the notes without eye contact; filling every pause with "um" instead of a silent, confident beat.
