lip sync

Lip sync, lip-sync, lip-synch (short for lip synchronization) is a technical term for matching lip movements with prerecorded sung or spoken vocals that the listeners hear, either through the sound reinforcement system in a live performance or television or cinema speakers in other cases. The term can refer to any of a number of different techniques and processes, in the context of live performances and recordings.
In film production, lip-synching is often part of the postproduction phase. Dubbing foreign-language films and making animated characters appear to speak both require elaborate lip-synching. Many video games make extensive use of lip-synced sound files to create an immersive environment. In the music industry, lip-synching can be controversial to fans attending concert performances who expect to view a live performance.
