How to add an AI voiceover to a screen recording

By Explaino Team · Updated October 11, 2026 · 5 min read

Quick answer

To add an AI voiceover to a screen recording, transcribe what you said, clean the script (remove filler words and tighten sentences), pick an AI voice or clone your own, then regenerate the narration so it stays in sync with your on-screen actions. Explaino does all four steps automatically after you stop recording.

Step by step

1
Record with your own voice first
Talk through the task while you record. Your voice gives the timing: where you pause and what you point at. It doesn't need to be polished.
2
Transcribe and clean the script
Turn the audio into text and remove ums, repeats and false starts. Shorten long sentences; spoken scripts should be simpler than written ones.
3
Choose a voice
Pick a voice that fits your audience and language, or clone your own voice from a short sample so every video sounds like you.
4
Regenerate the narration in sync
Generate the new voice line by line and align each line to the action it describes, so the viewer hears 'click Export' as the cursor clicks Export.
5
Review pronunciation and pacing
Check product names, acronyms and numbers. Fix any mispronunciation by editing the script or adding a phonetic spelling.

Why teams switch to AI voiceover

Most people who record software tutorials are not voice actors. Re-recording narration until it sounds smooth takes longer than the recording itself. An AI voiceover keeps your timing and content but removes hesitation, background noise and accent concerns, and makes it easy to change a sentence later without re-recording.

It also unlocks translation. Once the narration is a clean script, the same video can be voiced in other languages.

Voice cloning, briefly

Voice cloning creates an AI voice that sounds like a specific person from a short sample. Explaino can clone a voice from a sample of about 30 seconds, so a founder or trainer can keep their own voice across every video and language. Only clone a voice you have permission to use.

Record it once. Explaino does the rest.

Turn one screen recording into a narrated video with smart zoom and captions, plus a step-by-step article, in 70+ languages.

Frequently asked questions

Will an AI voiceover stay in sync with my screen?

It does if the tool aligns narration to your original timing. Explaino regenerates the voice segment by segment against the recording, so actions and words line up.

How many languages can the voiceover use?

Explaino's AI voices cover 70+ languages, so the same video can be narrated in each of your customers' languages.

Can I edit the voiceover later?

Yes. Edit the script text and regenerate only that line; you don't need to re-record the screen.
