It is like giving a dubbed movie a secret mouth coach. The new words play. The lips hit every cue.
It makes dubbed films and local videos feel less awkward. It also helps digital people look more real.
TTS
TTS creates the new spoken lines. Lip-sync then matches the lips to them.
Voice cloning
Voice cloning can keep the original actor's voice in the new dub.
Digital human
Lip-sync helps a digital human look natural while speaking.
