Steps
Make the voice-over
Type or paste the script. Write numbers and abbreviations the way they should be spoken, and add [pause 2] where you want a two-second pause. Pick the voice, the speed and the pause between sentences, listen, then download.
Trim it (optional)
Cut a breath or a pause at the start or end. Select the part to keep and download it as MP3 or WAV.
Put it on a video (optional)
Add your video. Choose whether its own sound is lowered under the voice (by 14 dB unless you change it), kept, or removed, and when the voice starts. The picture is copied as it is, so there is no quality loss.

FAQ
Can I use the voice-over commercially?
The Kokoro model is released under the Apache 2.0 licence, which allows commercial use. Nothing is added to the audio.
Does it sound like ElevenLabs?
It is a small open model that runs on your device, so it is not the same: it is clear and natural for narration, with fewer voices and less emotion control.
