This book explores the evolving art of public speaking, a timeless skill rooted in persuasion, leadership, and teaching -- as it undergoes a profound transformation in the age of artificial intelligence and immersive technologies. How often have we found ourselves preparing a presentation -- whether for work, a startup, or a company -- sitting at home or in the office, gripped by performance anxiety? We search for the right words, the perfect slides, the ideal script… all driven by the desire to finally feel prepared. Artificial Intelligence (AI) is revolutionizing not just how we work, but how we create, communicate, and train. For example, Bank of America’s iCoach project uses metaverse simulations and AI feedback to guide employees through difficult conversations. An impressive 97% of users report feeling more confident in their roles. Similarly, a study co-developed by Intel and HTC Vive found that immersive training increased motivation, reduced costs, and delivered a 300% ROI. Since 2020, the use of virtual reality in corporate training has quadrupled, with organizations increasingly adopting immersive environments for public speaking rehearsals, interviews, and digital events. Yet, traditional communication training remains largely unchanged—still rooted in classical rhetorical models, with little guidance for hybrid, AI-enhanced, or fully virtual contexts. This book fills that critical gap. It redefines public speaking by integrating emerging dimensions such as human-machine interaction, avatar-mediated communication, AI-generated speech, and virtual presence. The book is divided into three parts: the first, Principles, includes three chapters. From the basics of icebreaking, the foundation of storytelling, to the augmented creativity that can be applied for the realization and improvement of a pitch or speech. It comprises three interviews with global experts: Damian Scavo, founder of Streetbeat; Alvin Wang Graylin, a technological leader, author, and entrepreneur; Davide Viglialoro, a lecturer in Strategy and Entrepreneurship; and Canto i Fatti, a case study of innovation in social channels that uses AI-powered storytelling in novel ways. The second part of the book is Augmented Rhetorics. Rethinking Speech in the Age of Technology, which includes two chapters: Train Your Thinking and The Evolution of the Words. An analysis that starts with the types of thinking and moves to two relevant skills, part of our humanity: reading and writing. Then, the linguistic intelligence and its role with the advent of prompt engineering. Moreover, two interviews: the first with Francesco Frasca, a two-time world champion in bench press powerlifting, and the second with Francesco Finazzi, Founder and CEO of Mindoor, a start-up that addresses one of the most pressing challenges: mental well-being. And the last, Augmented Speaker, with three chapters that prepare the reader for the first simulation of public speaking in virtual reality, from technical headset settings to possible features. Then, how to build a long-term strategy across the five levels, introduce AI agents, outline their applications, and create a continuous improvement loop. The latest chapter, From Zero to Pitch, is only an exercise in improving prompting and pitching. Moreover, two interviews, one with Professor Jemery Bailenson, a communication professor at Stanford University and the founding director of the Virtual Human Interaction Lab, and the second with Alberto Tono, an expert in artificial intelligence and a PhD in Computer Science from Stanford. Last but not least, the analysis and presentation of a new platform, VoxcoachAI, were launched as part of this book's case study: for receiving real-time AI feedback, practicing with interactive roleplay, tracking progress, and improving your public speaking, presentations, and pitches.
