One of the most inspiring speeches I have heard from a woman was delivered by author and feminist, Isabel Allende at the TED conference in 2008. A great model for all aspiring women speakers. What we can all learn from this speech is the power of storytelling.
I recently read some public speaking advice for women suggesting using video to analyse your faults and then writing out the speech in full. I believe that advice is exactly what you MUST NOT do because it will heighten your stress and anxiety and result in a boring speech. A better approach is to focus on getting the content right and let the presentation take care of itself.
