I'd give the girl a speech lesson free for being useful. She needs to relax the shoulders, slow down and put moments of strong emotion when she does at the key points, if she wants to keep hard informative content. If she wants to go more humourous, the sarcastic style is effective, but you gotta make the disrespectful looks and eye rolls when you do. Humor forms a light connection that allows trust for deeper ones. The speaker must captivate and capitalize. Give me an hour a day a week she'll be a little Rav Kahanette.
