To help you or improve your own speaking , let me know:

Our hands and eyes often speak louder than our voices.

A monotonous voice is a lullaby; a dynamic one is a story.

Beyond the mechanics, effective speech is rooted in sincerity. When a speaker is authentic, their voice carries a natural resonance that no amount of rehearsal can mimic. Whether you are addressing a boardroom or sharing a story with a friend, the goal is "Etki" (Impact). You want your words to linger in the room long after you have stopped speaking.
