Speaking involves vocal communication to convey thoughts and information to others. It is one of the key language skills and involves more than just pronouncing words. There are different types of speaking situations from informal conversations to formal presentations that can be interactive, partially interactive, or non-interactive. Good speaking skills include being prepared, knowing the audience, keeping the message concise through structures like an opening, body and conclusion, interacting with the audience, speaking with passion and sincerity, and closing memorably. Fluency and overcoming barriers like unclear messages are also important for effective speaking.
