LOL!!
Lipreading (I am showing my age) is only effective when there is some auditory input, either with or without CI's or HA's. It is a natural process for those who do it.
A scary story. Late one night, there was a banging on my front door. I got up, and answered the door. I was not wearing either HA's or glasses. When I opened the door, I thought someone was celebrating Halloween out of season. The guy there had been attacked with a knife, and his upper lip was in shreds. I could not understand what he was saying, except "A friend did this to me." I guided him to the kitchen, away from the carpet, sat him on a chair, and called 911. Luckily, when it came time for the trial of his "friend," he decided to plea-bargain at the last minute, so I didn't have to explain my lack of knowledge about what he was saying. Argument over a bag of MJ, I found out later.
