How to Speak So That People Want to Listen | Julian Treasure | TED

The human voice and its power to effect change are explored, highlighting habits that undermine effective communication. Seven "deadly sins" of speaking are identified: gossip, judging, negativity, complaining, excuses, exaggeration, and dogmatism. To counter these, the acronym "HAIL" (honesty, authenticity, integrity, and love) is presented as cornerstones for powerful speech. Practical vocal techniques are shared, including register, timbre, prosody, pace, pitch, and volume, alongside vocal warm-up exercises to prepare for important speaking engagements. The discussion concludes with a vision for a world where sound is consciously created, consumed, and designed for understanding.
