Free AI Video Generator With Sound
Most AI videos are silent. These are not: picture, sound effects and speech are generated together, so your clip is ready to post.
Adding sound to a silent AI clip usually means hunting for stock effects and lining them up in an editor. Audio-video models skip that step: they generate the sound as part of the video, so footsteps land on the beat and waves crash when they hit the rocks.
JollyAI has two of these models: MiniMax H3 (free and PRO) and LTX 2.5 (PRO). Start from a text prompt or animate your own photo.
Kinds of Sound You Can Get
Ambience
Rain, wind, forest, ocean, city traffic, cafe chatter.
Sound Effects
Engines, footsteps, splashes, sizzling food, doors, applause.
Speech
A short line of dialogue in quotes, spoken by the character.
Simple Music
A soft piano, a jazz sax or a light beat in the background.
How It Works

Tips for Better AI Audio
- Name two or three sounds, not ten. The model focuses better.
- Match sound to action: if a glass breaks on screen, mention "glass shattering".
- Keep dialogue short and put it in quotes.
- Ask for quiet ("calm, quiet room") when you want clean speech.
Prompts to Try
Campfire
A campfire crackles under a starry sky, sparks rise, crickets chirp, a guitar strums softly nearby, static wide shot.
Thunderstorm cafe
View from inside a cozy cafe as rain pours outside the window, thunder rumbles, a spoon clinks in a cup, warm lamp light.
