A technique that maps the phoneme sequence in audio to corresponding mouth-shape poses, aligning mouth movement precisely with speech rhythm. It must handle complex factors such as coarticulation and emotional prosody.
Core Facts
Timeline (last 90 days)
Lip-sync technology typically relies on aligning the phoneme sequence of speech with the corresponding facial muscle movements (visemes) through mapping.
For videos that are primarily voiceover-based rather than on-camera presentations, the lip-sync feature can be skipped to reduce costs, as lip-sync increases costs and significantly extends processing time.
