Chapter 10 discusses the multisensory perception, like lip reading. I have never really thought about lip reading and how often it is done and how much it is used since the day you are born. You lip read when you are in a quiet environment, learning a new language, as well as when you were learning your first language. The McGurk effect relates to lip reading, it demonstrates that we all lip-read and use visual speech information. I find it really interesting that this effect is used as a tool for us to understand the type of facial information we require for visual speech perception. We have always lip-read according to a study on a five-month-old baby. Babies perceive speech from faces.
