Here is an interesting article about voice pacing on the BBC web site. Researches analyzed voice patterns of 1,400 attempts to get people to do a phone service. Here they are:
  • Speak moderately fast
  • Pause
  • Don't change the pitch of your voice too much
You could re-write these findings as follows:
  • Be energetic and enthusiastic
  • Don't rattle off a pre-programmed script
  • Act normal
In short, have a human conversation.
