How to Record a Voice-Over for a Slideshow
Updated October 2026
A slideshow with a clear voice-over explains itself. Write one line per slide, time it, record in a quiet room and keep the voice steady from slide to slide.
The short version
- Write one short line for each slide.
- Time the lines against the slides before you record.
- Record in a quiet room with the mic close and steady.
- Clean and level the voice, and align it slide by slide.
Script per slide
Write one or two sentences for each slide, and say only what the slide does not. Read the script aloud and time it, so each line fits its slide.
Record in sections
Record one slide at a time, so a stumble is easy to re-record. Keep the mic distance and the level the same across the sections.
Clean and align
Clean the voice gently and level it. Place each line on its slide, and leave a short pause before a new slide, so the viewer can see the change.

Frequently asked questions
How long should each line be?
As long as the slide needs and no longer. Time it aloud.
Should I record the whole show at once?
No. Record in sections, so re-takes are easy.
Can I use music under the narration?
Yes, if you have the right to use it. Duck it under the voice.
