Add sound to a video
The short answer

Tips and limits
- A model with no sound switch either always adds sound or makes none. Its line in Models ends with Sound when it adds it.
- Put spoken words in quotes in your prompt, and say who says them.
- See every model that makes sound on the AI video with audio page.
If something goes wrong
- The video came out silent: the model makes no sound, or the switch was Off. Pick a model whose line ends with Sound.
- The button says Top Up instead of Generate: your balance is too low for this video.
- The video failed: a failed render gives its credits back.Fix
