Short Answer:   No.

Long Answer:   The time is passed when a Speaker or Presenter can arrive at a Speaking Event expecting Powerpoint, Keynote, or a Slideshare deck to do the Presenting. Todays’ Audience will no longer accept that decision from a Speaker. If you attempt it, you will annoy the Audience who may well ignore you & your message. You’ll ruin your chance for a successful outcome. So, don’t waste your time or that of the Audience.

If you decide to use any Presentation program like Powerpoint or Keynote, follow the Best Practices of building a Presentation. There are numerous books and websites with suggestions re: best colors, font’s, bullet points, images, etc… do the research.

Powerpoint should Support not “Be” the Presentation

---

Whatever Presentation program you use, the Presentation should be designed to Support your verbal presentation. The audience came to see-and-hear You deliver the information, and Powerpoint is supporting You. A point to remember: Keep your Back to the Slide-show, not to your Audience.

A Skilled Speaker can succeed even with a weak Presentation, but a weak Speaker, even with a good Presentation, rarely succeeds. What do you want the Audience to Take-away from your Presentation?

Speaking is a Learnable Skill. Every verbal interaction is a "Conversation" and we all engage in Conversations everyday. Learn to confidently participate in Conversations that need & want your perspective.
