Yeah we all “Lip Read”… Even the folks with perfect hearing. The pandemic was a rude awakening for hearing folks, as well as HOH… My A.uD said as much, and she has perfect hearing, she struggled badly with face masks! Only approximately 30% or so words a clearly distinguishable on the lips though, the rest we get from facial expressions, body language, in our search for contextual information, and some words, for instance “Bees” & “Peas”, these are indistinguishable because of their lip pattern, it is as we all know very easy to misinterpret a key word, and subsequently derail a conversation, in some cases with hilarious consequences, or in others perhaps acute embarrassment… Lip Reading (so called here in the UK) isn’t an exact science, it is more of a visual assistance to hearing, and yes you can become very skilled in Lip Reading, in the UK they run various Lip Reading classes, I have done a few courses over the years, they where always fun to learn, and making a complete fool of yourself in front of your fellow students, was common place… Cheers Kev
