Prompting for Built-In Audio

Glissez pour afficher le menu

Veo 3.1 generates sound as part of the video, not as a separate step. Describe audio the same way you describe visuals — just add an "Audio:" line.

Audio: soft rain ambience, distant thunder, a woman quietly humming.

You can prompt for:

  • Ambient sound — rain, traffic, wind
  • Sound effects — footsteps, a door closing
  • Dialogue — short spoken lines, synced to lip movement
  • Music — a simple mood cue like "soft piano in the background"
Note
Note

Keep dialogue short — one sentence or less. Long spoken lines are harder for the model to sync accurately with lip movement.
