Seeing at the Speed of Sound

Seeing at the Speed of Sound "Even the most skilled lipreaders in English, I have read, can discern an average of 30 percent of what is being said. I believe this figure to be true. There are people with whom I catch almost every word—people I know well, or who take care to speak at a reasonable rate, or whose faces are just easier on the eyes (for lack of a better phrase). But there are also people whom I cannot understand at all. On average, 30 percent is a reasonable number.

But 30 percent is also rather unreasonable. How does one have a meaningful conversation at 30 percent? It is like functioning at 30 percent of normal oxygen, or eating 30 percent of recommended calories—possible to subsist, but difficult to feel at your best and all but impossible to excel. Often I stick with contained discussion topics because they maximize the number of words I will understand. They make the conversation feel safe. 'How are you?' 'How's school?' 'Did you have a nice night?' Because I can anticipate that the other person will say 'Fine, how are you?' or 'Good,' I am at lower risk for communication failure."
