I've hear both claims1) people (in general) talk faster than listeners can process the meaning of the words being said2) people can process what's being said faster than a person can talkI think 2) comes from the fact that sometimes you can predict the end of a sentence before it is spoken. Have there been any studies that verify that people speak faster than can be understood or vice-versa? 
Do people talk faster than they process?
