kling-lip-sync

Create an asynchronous lip sync video generation task. The facial movements in the source video are re-animated to match the provided speech.

Prerequisite: call the identify-face endpoint first to obtain a session_id.

Two input modes are supported:

Text mode — provide text, voice_id, and voice_language. The platform converts the text to speech using the specified voice and drives the lip movements.
Audio mode — provide audio_url. The lip movements are driven directly by the supplied audio file.

After submission, poll GET /kling/v1/videos/advanced-lip-sync/{task_id} until status is succeeded.
