The surprising secret to speaking with confidence
Caroline Goyder | TEDxBrixton
Nov 25, 2014

This talk was given at a local TEDx event, produced independently of the TED Conferences. In this fun and personal talk, Caroline shares a story of moving from stage-paralysis to expressive self. Accompanied by an unusual prop, she encourages us to use our voice as an instrument and really find the confidence within.

Caroline Goyder is an author and voice coach, with a lifelong curiosity in the question of how we find the courage to think for ourselves: aloud. Caroline trained as an actor, and then as a voice coach at Central School of Speech and Drama (CSSD), where she worked for ten years. She now runs a business that helps people find confidence and calm in the theatre of life. Caroline is the author of Gravitas: Communicate with Confidence, Influence and Authority (Ebury)

2. Don’t go too far down the rabbit hole.
3. Clarity beats accuracy

4. Explain what you think is cool
