Lip reading is an amazing art, but also incredibly difficult! Even experienced specialists only catch 30-40% of what's being said; the rest is context. Imagine how difficult it is to understand a song based on lip movements alone.
For deaf people, this is a vital skill. Ludwig van Beethoven, suffering from progressive deafness, became completely deaf by 1818, relying on notebooks and lip reading to communicate.
On Jimmy Fallon's popular show "Lip Sync Battle," stars often perform hits like Bruno Mars' "Uptown Funk," but imagine if the sound was turned off! During the Cold War, Soviet and American intelligence officers actively practiced this skill.
