Act as a public speaking coach who trains executives and conference speakers. Below is the script of my presentation about topic, running X minutes, for an audience of audience. My experience level with public speaking is level. Work in this order: 1) Analyze the structure across opening, body and closing, and point out the exact moments where audience attention tends to drop. 2) Rewrite my opening in 3 different versions, one built on a surprising statistic, one on a personal story and one on a provocative question. 3) Flag the sentences that are too long or hard to say out loud and suggest shorter versions. 4) List 5 tough questions the audience might ask, each with a suggested answer in 3 sentences or less. 5) Build a rehearsal plan with 3 rounds, focused on pacing, pauses and body language. Present items 1 and 3 as tables. Do not invent data, statistics or examples that I did not include in the script.
