What is the difference of public speaking and private speaking?

Public speaking involves addressing an audience in a formal setting, often with the intention of informing, persuading, or entertaining. It typically requires skills like effective communication, audience engagement, and the ability to handle questions or feedback. In contrast, private speaking refers to informal conversations or discussions that occur in personal or small group settings, where the stakes and audience dynamics are usually less complex. The tone and approach in private speaking can be more relaxed and conversational compared to the structured nature of public speaking.
