How much of what a person says can a lip reader understand? What if they have a heavy accent because your language is not their first language – does that make a difference? Tina Lannin is an expert lip reader and in her article she explains the ins and outs of lip reading. She claims it is possible to understand all that is said but much depends on context. As for foreigners, it is not the accent that matters but the clarity of the speech. And of course, you can’t lip read words that you don’t know, so having a good vocabulary is essential for lip reading. Tina also works as an expert witness forensic lip reader. We can all help lip readers by facing them, not mumbling to our shoes, and speaking as we would to anyone else. And also making sure the faces of conference speakers are well lit. The article is titled, Can a deaf person read lips from a foreigner that speaks that person’s language?
