To add AI voiceover to a video, write your script in Morphic, generate a voice and direct its tone and pacing, then bring the voice and the video onto the Compose timeline and line the read up with the footage. No recording booth or separate audio app is needed, and nothing is exported between tools.

Add your voiceover step by step
1.
Write or paste your script
Start from the words you want spoken. Paste an existing script or write one in Morphic, and read it aloud once to check the pacing, since a line that looks fine on the page can run long when spoken. Break it into short sentences at the points where the video changes, so each spoken beat has a matching moment on screen. A tight script is the single biggest factor in a voiceover that feels made for the video rather than laid over it.
2.
Generate a voice and direct it
Generate the read with the AI voice generator and treat the first pass as a draft. Pick a voice that suits the piece, then direct how it performs: set the emotion, add emphasis, and control the pacing so it sounds spoken rather than recited. If you would rather use your own take, the voice changer can convert a recording into a different voice, though cloning your exact voice from a sample is not yet available.
3.
Add the video and voiceover to Compose
Bring both the footage and the generated voice onto the Compose timeline. Keeping them in one place is the point: there is no round trip to a separate voice tool and back, so the read stays in sync with the picture as you work. Lay the voice on the audio track and position the video above it, ready to align in the next step.
4.
Sync the read to the footage
Line the voice up with the video so the words land on the right moments. Trim or nudge clips so a point made in the narration matches what is on screen when it is said, and cut on the natural pauses in the read. If a line runs long or short against a shot, adjust the clip length rather than rushing the voice, and add styled captions if you want the words on screen too.
5.
Balance the audio and export
Set the levels so the voice sits clearly above any music or ambient sound, using per-clip volume so nothing fights the narration. Music should support the read, not compete with it, so keep the bed low under spoken lines and let it rise only in the gaps. Listen through once end to end for pacing and clarity, on both speakers and earbuds, and fix any line that lands early or late against a cut. Then export: free exports carry a watermark, and a paid plan exports clean and at higher resolution for anything you are publishing rather than testing.
AI voiceover versus the alternatives
Voiceover used to mean a mic, a quiet room, and takes. Here is how the AI route compares, Morphic first but not the only option.
| AI voiceover (Morphic) | Record it yourself | Hire a VO artist | |
|---|---|---|---|
| You need | A script | A mic and a quiet room | A budget and a brief |
| Time to first take | Minutes | An afternoon of recording | Days of back-and-forth |
| Revisions | Regenerate instantly | Re-record the line | New session or fee |
| Languages | Many, from one script | Only what you speak | One per hire |
If the video should look like a person is speaking the words, pair the voiceover with AI lip-sync so a face matches the read. For the full start-to-finish flow, the how to make an AI video guide covers generating the footage the voiceover sits on.
Put it together
A good AI voiceover is a tight script, a directed read, and clean sync. Write in short beats that match the cuts, direct the voice so it performs rather than recites, and line it up on the Compose timeline so the words land with the picture. Do that and the narration sounds made for the video, not dropped on top of it, in a fraction of the time a recording session would take.
