A great voiceover turns raw footage into a finished video — but recording one yourself means gear, a quiet room, and lots of retakes. Here's how to add a natural AI voiceover to any video for free, in minutes.
1. Write a tight script
Watch your footage and write narration that fits the pacing. Keep sentences short and conversational — you're writing for the ear, not the page. Note roughly where each line should land in the video so timing is easy later.
2. Choose a voice that fits the video
Pick a voice that matches your tone: calm and warm for tutorials, bright and upbeat for promos, clear and neutral for explainers. Preview a few options before committing — the right voice makes the whole video feel more professional.
3. Generate the narration
Paste your script, pick a style preset like Conversational or Narration, and generate. Listen back and fix any awkward lines by tweaking punctuation or spelling, then regenerate just those parts. Export the audio as an MP3.
4. Drop the audio into your editor
Import the MP3 into any video editor, place it on the audio track, and nudge each line to line up with the visuals. Lower any background music under the voice so the narration stays clear.
5. Localize it for more reach
Want to reach a global audience? Generate the same script in other languages, or use AI dubbing to translate and re-voice the whole video while keeping a consistent sound. It's the fastest way to multiply your views.
