How to Generate AI Video with Native Audio Using Veo 3.1

AI Video with Native Audio

Veo 3.1 is the first mainstream AI video model that generates synchronized audio alongside video. Dialogue, sound effects, ambient noise, and music — all from a single text prompt. Here's everything you need to know.

What Makes Veo 3.1 Audio Different

Previous AI video models generate silent clips. Veo 3.1 generates audio that is:

• Perfectly synchronized with visual events
• Contextually appropriate (rain sounds for rainy scenes)
• Includes dialogue with accurate lip sync
• Supports ambient environmental sounds
• Can include music as part of the scene

Writing Prompts for Audio

To get the best audio output, explicitly describe the sounds you want:

• Environmental: "heavy rain hitting windows, distant thunder rolling"
• Dialogue: "a woman saying 'good morning' warmly"
• Music: "a soft piano melody plays in the background"
• Ambient: "busy coffee shop sounds, espresso machine, quiet chatter"

Cost and Settings

Veo 3.1 on PulseMotionHub costs 10 credits per 8-second clip with audio. Veo 3.1 Fast costs 5 credits for the same duration at slightly lower quality. Both are in the 💎 Premium Video tab.
