lipsynced

Lipsynced is the past participle and adjective form of lip-sync, referring to an alignment between lip movements and an audio track. In practice, something described as lipsynced is produced or performed with the lips synchronized to the voice or sound that is heard, which may be the original recording or a separate track. Lip-syncing is widely used across media to control sound quality, timing, and performance constraints, or to render dialogue in different languages.

In live performance and broadcasting, performers may lipsync to a studio-recorded song or vocal track while dancing or performing choreographed movements. This approach is common in televised musical acts, award shows, and certain stage productions where live singing is impractical or would introduce unwanted variability. In film and television production, lip-syncing often involves post-production techniques such as automated dialogue replacement (ADR) or re-recording to ensure dialogue matches lip movements, especially in noisy environments or when blending multiple takes.

In animation and dubbing, lip-syncing is a core technique for matching character mouth shapes to spoken dialogue; in dubbing, translators adapt the vocal track to fit the characters’ lips and timing. In video games and virtual productions, real-time or pre-processed lip-syncing is used to create natural-looking character speech, frequently incorporating viseme-based animation to enhance realism.

Quality control emphasizes timing accuracy, phoneme-to-viseme correspondence, and naturalistic movement. When performed well, lipsynced sequences appear seamless; when misaligned, they can appear distracting or inauthentic.
