Lip reading, also known as lipreading or speechreading, is a technique of understanding speech by visually interpreting the movements of the lips, face and tongue with information provided by the context, language, and any residual hearing.
People with normal vision, hearing and social skills sub-consciously use information from the lips and face to aid aural comprehension in everyday conversation, and most fluent speakers of a language are able to speechread to some extent (see McGurk effect). Each speech sound (phoneme) has a particular facial and mouth position (viseme), although many phonemes share the same viseme and thus are impossible to distinguish from visual information alone. To appreciate how difficult lip reading is, and how much of the articulation of normal speech is not visible to an observer who cannot see "the inside of the speaker's head", it helps to watch an MRI video of a person speaking. When a normal person speaks, the tongue moves in at least 3 places (tip, middle and back), and the soft palate rises and falls. All of these articulatory gestures are phonetically significant, changing the speech sound produced in important ways, but are invisible to the lip reader.

I once knew a kid
Whose tongue fell off in his sleep,
La-Bibbida-Bibba-Dum
What?
La-Bibbida-Bibba-Do
The girl in my basement
Probably thinks I'm a creep
Yeah, probably
La-Bibbida-Bibba-Dum
La-Bibbida-Bibba-Do
I've got,
9 cases of anti-fungal ointment that
Nobody can use without appointment
Down in
Woodberry (Woodberry, Woodberry)
Is that your little play-town?
Where it's very
La-Bibbida-Bibba-Dum
La-Bibbida-WHAT?
La-Bibbida-Bibba-Dum
Give me your bubble gum!
Now what makes you think I have gum?
Yeah, well I found out from Orlando
That biter that was a handyman
Woah, you got a handyman that's a walker?!?
Well to be honest
He breaks more things than he fixes
But he's still got most of his face
So, I trust him
(Heads in aquariums, heads in aquariums)
I own heads in aquariums
And don't find them scary
I'm fond of Bavarian cream
My dream of
La-Bibbida-Bibba-Dum
La-Bibbida-Bibba-Do
La-Bibbida-Bibba-Dum
Dum-Dum, Dum-Dum-Dum...
Starfish command!
You know what?
Not even going to bother with that
Ricardo,
If you have to ask
You'll never know
My uncle was tall
But had these really short legs
La-Bibbida-Bibba-Dum
La-Bibbida-Bibba-Do
I wonder if poodles in Jamaica
Have dreads
La-Bibbida-Bibba-Dum
La-Bibbida-Bibba-Do
This is a violet
No it isn't
Yeah, well it could be a flower
The other night there was this movie all about gardens
Called "Bloody Shrimp"
You got a problem?
Uh, yeah
I just found out that we missed Halloween
I always wanted a Wookie
But I found out they weren't real
Thanks for nothing, George Lucas

Cluck went the chicken!
And that's how they do it
