), it is more often used by recording artists to create a particular effect, to enable them to perform live dance numbers, or to cover for illness or other deficiencies during live performance. Sometimes lip-synching performances are forced by television for short guest appearances, as it requires less time for rehearsals and hugely simplifies the process of sound mixing. Some artists, however, lip-synch as they are not as confident singing live and lip-synching can eliminate the possibility of hitting any bad notes. The practice of lip synching during live performances is frowned on by many who view it as a crutch only used by lesser talents.

 broadcast. However, cinematic releases of films tend to come with subtitles instead. The same is true of countries in which the local language is not spoken widely enough to make the expensive dubbing commercially viable (in other words, there is not enough market for it).

However, most non-English-speaking countries with a large enough population dub all foreign films into their national language cinematic release. In such countries, people are accustomed to dubbed films, so less than optimal matches between the lip movements and the voice are not generally noticed . Dubbing is preferred by some because it allows the to viewer focus on the on-screen action, without reading subtitles.

In video games

Early video games did not use any voice sounds, due to technical limitations. In the 1970s and early 1980s, most video games used simple electronic sounds such as bleeps and simulated explosion sounds. At most, these games featured some generic jaw or mouth movement to convey a communication process in addition to text. However, as games become more advanced in the 1990s and 2000s, lip sync and voice acting has become a major focus of many games.

used full motion video character portraits with several generic speaking animations that did not synchronize with the lines spoken in the game. The game did, however, make extensive use of recorded speech to convey the game's plot, with the speaking animations providing a good idea of the flow of the conversation. Warcraft III used fully rendered 3D models to animate speech with generic mouth movements, both as character portraits as well as the in-game units. Like the FMV portraits, the 3D models did not synchronize with actual spoken text, while in-game models tended to simulate speech by moving their heads and arms rather than using actual lip synchronization. Similarly, the game Codename Panzers uses camera angles and hand movements to simulate speech, as the characters have no actual mouth movement.

First-person shooters

FPS is a genre that generally places much more emphasis on graphical display, mainly due to the camera almost always being very close to character models. Due to increasingly detailed character models requiring animation, FPS developers assign many resources to create realistic lip synchronization with the many lines of speech used in most FPS games. Early 3D models used basic up-and-down jaw movements to simulate speech. As technology progressed, mouth movements began to closely resemble real human speech movements. Medal of Honor: Frontline
