How to Add a Voiceover to a Screen Recording

The short version

Write or outline the script, then record the voice against the screen.
Record the voice in a quiet room with the screen’s own sound off.
Leave a short pause before each new step so the viewer can see what changed.
Clean the voice and balance it under any music.

Script the steps

A short outline with one line per step is enough. Read it aloud once with a timer to see how long each step takes. Speak to the screen: name the thing the viewer should look at, then say what it does.

Record the voice

Record the voice in a quiet room, away from the computer fan. Mute notifications and other audio so the recording is clean. Record step by step, one take per section, so you can replace a single bad line without re-recording the whole tutorial.

Line it up with the screen

Place each section of the voice against the matching part of the screen recording. Leave a short gap before a new step, so the viewer sees the change before the voice explains it.

Balance it

If the screen has sound or music, lower it under the voice, not the other way round. Check the balance on a laptop speaker, which is what many viewers will hear.

Clean and export

Clean the voice gently, then export the mix at a loudness target for online video.

Frequently asked questions

Should I record the voice first or after the screen?

Record the voice against the finished screen recording, so the timing matches the actions.

How do I stop the computer fan being picked up?

Turn the fan down, or record with the laptop on a stand away from the mic.

Is there a free way to do this?

Yes. Any recorder for the voice and any free editor for the mix will do the job.
