Evaluations

2. How are these speeches "audience centered"?

These speeches are audience centered because they both can affect audience members.  In the Robot speech, the speaker says how family members that you know may now be treated by medical robots, and that it is becoming much more common.  In the Chili Pepper speech, he relates it to the audience by showing common uses by any ordinary person, and also gives advice on how to tame the heat, both information that the audience can take away.

6. Choose one of the two speeches: Comment on delivery and non-verbal communication. Was it effective? Explain your answer. 

For the Chili Pepper speech, his delivery was very good.  He was using non verbals, mostly gestures, that kept my attention.  He also, by his body language, seemed genuinely interested in his topic, which made it very engaging.
