Susan C. Young said this quote
“ As a professional speaker, I speak rather quickly with enthusiastic energy and emotion. This doesn’t always sit well with people who like to speak at a slower pace and need more time to process. What I have learned through years in this profession is that to be more effective I must adapt my pace to the comfort level of my audience. When I am speaking to academics, engineers, and doctors, I speak with a slower pace than the one which I use with sales people, customer services teams, or teenagers. ”
