Chapter 10 discusses the effects of lip reading. Below I provide the example from Late Night with Jimmy Fallon. In this clip he performs the Whisper Challenge. One person is given headphones with music playing where the other person mouths song lyrics. This leaves the person with the headphone on lip read what their partner is saying. In the video, you will notice at certain times they would focus on the lips of the player and were unable to determine the lyrics. The most effective approach happens when the whole face is observed during lip reading. Chapter 10 reiterates the most effective lip reading occurs by viewing the whole face. This is a good experiment to try with friends to test out your lip-reading skills.
