AI Music Generator for Videos

Type a prompt, get a soundtrack — or a voiceover. Leonardo.Ai generates music and speech in the same workspace where you make your images and videos. Free to start — if you can describe a feeling, you can score a scene.

What is an AI music generator?

An AI music generator turns a text description into audio. Describe the sound you want — the genre, mood, and instrumentation — and shape a track to match. No instruments, no DAW, no music theory required.

Leonardo offers the latest audio models, including Music v1 for music tracks and Seed Audio 1.0 for AI voiceover. They live alongside the image and video generators — so the clip and its soundtrack come from the same workspace.

Describe your sound

A short prompt sets the genre, mood, and energy — and the track takes shape around your direction.

Tracks with Music v1

Compose music from a prompt — tracks from one to ten minutes, with vocals or fully instrumental.

Voiceover with Seed Audio 1.0

Turn a script into speech with a library of AI voices — control the pace, pitch, and delivery.

One creative workspace

Images, video, 3D, and audio generated in a single studio — one platform, one login.

From clip to scored scene

Generate your video, then prompt Music v1 for the soundtrack it deserves — a track from one to ten minutes, matched to the mood you describe. Same workspace, one more generation.

Voiceover on cue

Write the script, pick a voice, and Seed Audio 1.0 reads it the way you direct — pace, pitch, and delivery under your control. Narrate a product demo, a story, or a how-to without recording a word.

Music track, voiceover, or native video audio?

Leonardo gives you three routes to sound, and each does a different job. Music v1 composes standalone tracks — a score you control independently of any clip. Seed Audio 1.0 turns a script into speech with a library of AI voices.

The third route is built into the video models themselves: models like Seedance 2.5, Kling 3.0 Turbo, MiniMax H3, and FLUX 3 Video generate synchronized audio — dialogue, effects, and ambience — in the same pass as the visuals.

They combine, too. Score a clip with a Music v1 track, narrate it with Seed Audio, or use audio as an input reference where models support it — Seedance 2.5 and Seed Audio 1.0 both accept audio references.

AIMusic&VoiceoverFAQS

Can I use the generated music commercially?

Yes — audio you generate can be used commercially, just like your images and videos. See the Terms of Service for the full details.

How do I add AI music to my videos?

Generate your clip with the AI video generator or turn a still into motion with image to video, then prompt Music v1 for a track that matches the scene — or pick a video model with native audio and get sound in the same pass.

Which audio models does Leonardo offer?

Leonardo always offers the latest audio models, including Music v1 for music tracks and Seed Audio 1.0 for AI voiceover. New models are added as they’re released.

What’s the difference between Music v1 and Seed Audio 1.0?

Music v1 composes music — soundtracks, beds, and themes from a text prompt, up to ten minutes long, with an instrumental-only option. Seed Audio 1.0 generates speech: give it a script, pick a voice, and direct the pace and pitch. Reach for Music v1 when you need a score, Seed Audio when you need a narrator.

Don’t some video models already generate sound?

Yes. Video models like Seedance 2.5, Kling 3.0 Turbo, MiniMax H3, and FLUX 3 Video generate synchronized audio in the same pass as the visuals. This page’s tools cover the rest: a standalone score you control separately, and a voiceover you can direct line by line.

Do I need any music experience to use it?

No. You describe the sound in plain language — the style, the mood, what it’s for — and the model handles the composition. If you can write an image prompt, you can write a music prompt.

Your soundtrack needs something to play under. Everything else lives one tab away.
