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.
