The term kararoke means to sing to an instruental version of  a recording with no vocal track. Have you ever participated?
imtoo shy to do karoke.h ave you ever tried?
I have not in a broad setting but i have as a child! It was super fun, but many people can confuse karaoke with lip synhing as in when a performer mimes to  a studio recording that actually includes the vocals.
ive  heard some famous people lip sync their performances
Yes, speaking of famous in 1961 network NBC had a karaoke series called "Sing along with Mitch" featuring Mitch Miller and a chorus which superimposed the lyrics to their songs at the bottom of the tv screen so those watching at home could participate. It was beyond my time but maybe that could have been good practice!
