# AI video with speech, music and ambience

Decide where the sound comes from first. Inventing speech and ambience with a scene is different from synchronizing a portrait to a finished recording. These tasks need different workflows.

## How to choose

For sound generated with video, explore Veo, Kling 2.6/3.0, Seedance 2.5 or MiniMax H3. Enable sound where a separate toggle exists.

For a specific recording, prepare audio first and use Kling AI Avatar. Without a voice track, synthesize the script in ElevenLabs first.

Separate dialogue, background ambience and music in the brief. Identify the speaker and leave time for the line. Check word endings and pauses after generation.

## FAQ

Does native sound guarantee perfect lip-sync?

No. Speech and articulation can differ; watch and listen to the result.

How do I avoid music?

Specify the soundscape and request only speech and necessary ambience. Switching off all sound is a different setting.

Can I fit a long script into a short clip?

Shorten the line or choose an appropriate duration. Overcrowded speech makes the scene harder to follow.
