How to speak so that people want to listen | Julian Treasure

I came across a learning talk from Julian Treasure on how to speak. Here is a summary of the talk made by Gil Su Kim in the youtube comment section which I find to be worth sharing. Let's enjoy the talk. The video is given at the end of this post.

1.  Seven deadly sins of speaking to avoid

1. Gossip -> I need to work on this sin
2. Judging -> I need to work on this sin
3. Negativity -> I need to work on this sin
4. Complaining -> I need to work on this sin
5. Excuses
6. Lying (embroidery, exaggeration)
7. Dogmatism (confusion between fact and opinion)

2. What I need to say
Four powerful cornerstones of speech to make a change in the world
c.f. "hail means to greet or acclaim enthusiastically"

1. H: honesty (be clear and straight)
2. A: authenticity (be myself)
3. I: integrity (be my word)
4. L: love (wish them well)

3. How I need to say
Tools to play with to increase power of my speech

1. Register: e.g. if wanting weight, lower pitch of voice
2. Timbre: the way voice feels e.g. breathing, posture
3. Prosody: rhythm (e.g. not monotone)
4. Pace: e.g. slow to emphasize
5. Pitch: e.g. make pitch high or low
6. Volume: e.g. louder to emphasize

4. Exercise the following before making a presentation

1. Arms up to sigh out with ahh
2. Lips with ba ba
3. Lips with brrr 
4. Tongue with la
5. Tongue rolling an r
6. Siren from we to aww
