Step by step

How to do a voiceover on a YouTube Video

  1. Generate the voice in Cantari: paste your script, pick a voice, and generate a natural read in seconds, then export the audio file (MP3 on every plan, WAV on paid plans). No microphone, no retakes.

  2. Generate your narration script as audio (one file, or one per section).

  3. In your video editor (Premiere, Final Cut, CapCut, iMovie, or similar), drop the audio onto a track under your footage.

  4. Line the narration up with the visuals, balance it against any music, then export and upload the finished video to YouTube.

YouTube itself does not record or add voiceovers; that happens in your editor before upload. So the question is really which editor, and each one's page here covers the exact steps. The narration is generated once and reused across every cut.

Straight answers

Voiceover on a YouTube Video, answered.

Does YouTube have a voiceover tool?
No. YouTube hosts the finished video; you add the voiceover in your editing app before uploading. YouTube Studio's editor only trims and blurs, it does not add narration.
What is the best way to narrate a YouTube video without recording myself?
Generate the narration from your script as an audio file, then drop it onto the audio track in your editor. It is clean, consistent, and easy to update.
Can I update the narration later without re-recording?
Yes. Re-generate the changed lines from text and swap the audio in your editor, then re-export. No microphone session required.
