AI-generated characters that speak need mouths that move convincingly. Poor lip sync breaks immersion instantly and makes content look amateurish. HappyHorse Lab mode provides precise control over speech-to-motion mapping, producing lip sync that matches audio cadence naturally — for UGC-style content, narrator-driven explainers, and character-based series where believable speech is non-negotiable.
操作步骤
- 1
Record or generate the audio narration track with clear pronunciation and natural pacing.
- 2
Select or generate a character reference with a clearly visible face at a consistent angle.
- 3
Run the lip-sync process to map audio phonemes to corresponding mouth movements.
- 4
Review the output for sync accuracy, especially on plosive sounds and sentence endings.
