How to Add a Voiceover to a Video (Free, No Mic Needed)

There are two ways to add a voiceover to a video: record your own voice, or generate an AI voiceover from a script — useful if you don't want to record, don't have a mic, or want a consistent voice. This guide shows the free way to do both, add the voiceover to your video with captions, and export — all in your browser, nothing uploaded.

Step by step

1. Write or paste your script. Open the free text-to-speech tool and type what you want said.
2. Pick a natural voice and generate. Choose from natural AI voices in several languages — they sound human, not robotic — and generate the voiceover instantly.
3. Or record your own. Prefer your real voice? Use the voice recorder to capture it in the browser.
4. Add it to your video. Send the voiceover into the free video editor and lay it over your clip.
5. Caption and export. Add word-by-word captions and export your video — free, no watermark.

AI voiceover vs. recording your own

Recording your own voice is personal and free, but needs a quiet room, a decent mic, and re-takes when you stumble. An AI voiceover reads your script in a consistent, natural voice every time — ideal for faceless videos, explainers, tutorials and social clips where you want a clean narration without recording. SnipSound does both for free.

Make it natural, not robotic

The knock on free voiceover tools is robotic voices. SnipSound uses natural neural voices that sound human, with word-perfect caption timing — so your narration doesn't give away that it's AI. It won't match a paid studio's most cinematic clone, but for free, private, unlimited voiceovers it's a genuine step up from the old robotic readers.
