Veo 3 Audio & Dialogue Prompt Generator

Veo 3 is one of the first AI video models with native audio — spoken dialogue, ambient sound, sound effects and music, all generated in sync with the picture. The trick is formatting. This free Veo 3 audio & dialogue prompt builder writes each spoken line in the format Veo responds to best: Character says: "..." — using a colon and quotes rather than bare text — and appends (no subtitles) so Veo does not burn captions into your footage.

Add a scene description, one or more dialogue lines, then layer in ambient sound, SFX and music. Copy the result straight into Veo 3 or Veo 4. Everything runs in your browser with no login, no limits and no cost.

Dialogue lines
Veo 3 generates native audio. Dialogue is written as Character says: "..." and (no subtitles) keeps captions off-screen. Build the full shot with the Veo 3 prompt generator.
How to use this tool
  1. Describe the scene so Veo knows the setting and who is speaking.
  2. Add each line of dialogue with the character and what they say — use Add line for more.
  3. Layer in ambient sound, SFX and music to build the soundscape.
  4. Keep 'No subtitles' on to avoid burned-in captions, then copy the prompt into Veo 3 / Veo 4.
Frequently asked questions
Why write dialogue as 'Character says: "..."'?
The colon-plus-quotes format clearly signals spoken dialogue to Veo 3, which makes it more likely to generate clean lip-synced speech instead of mumbled or muddled audio. Bare quotes alone are easier for the model to misread.
How do I stop Veo from adding subtitles?
Whenever you include dialogue, append '(no subtitles)' to the prompt — this builder adds it automatically when the checkbox is on. It tells Veo not to burn on-screen captions into the video.
Can I add sound effects and music too?
Yes. The builder prefixes ambient cues, SFX and music so Veo layers them correctly. For the full shot — camera, lighting and style — pair this with our Veo 3 prompt generator or the JSON prompt generator.
