Definition
A voiceover is narration recorded or synthesized separately from the visuals and heard during a video. It can explain a product workflow while the screen shows the relevant steps. Good voiceover supports the images rather than repeating every label, and should be reviewed for clarity, pronunciation, timing, and rights.
Scenario in a product workflow
In a feature video, narration can explain why a setting matters while the screen shows where it lives. A long line over a fast-changing screen is hard to follow, so coordinate script length, scene hold time and transitions. Ask a reviewer to listen without watching and then watch without sound to check both tracks.
How to apply it
Read the narration aloud or listen to the generated take with the video. Check pronunciation, pauses and whether the spoken line leaves enough time to understand the screen.
A practical review
Play the voice track with the visuals at normal speed. Check names, acronyms, pronunciation, volume, pauses and the time viewers need to inspect a screen. Listen on headphones and phone speakers before export.
A decision to make before production
Choose voiceover when narration adds explanation, context or pacing that the screen alone cannot provide. A silent preview should still communicate essential actions through visible cues and captions.
How it differs from text-to-speech
Voiceover describes narration as part of a video, regardless of how it was made. Text-to-speech is one way to produce speech from written text; recorded human narration is another.
When a team uses the term “voiceover” in a brief or review, agree on the intended meaning before production. That prevents the script, visual plan and success measure from drifting apart.
