Add narration without opening a full video editor
Voiceover editing sits between generation and publishing. This page keeps script writing, voice choice, audio mixing, and render output in one workflow.
Single-video narration workflow
Upload one clip, write the script, and render a voiceover version without switching to a full editor.
Built on existing TTS capability
The page reuses Vidrush text-to-speech workflow, then merges the generated audio back into the video.
Flexible audio replacement or mix
Replace the original track entirely or keep some of the source audio and layer the new narration over it.
Prepare narration that fits the video
The best results come from scripts that match clip length, visual pacing, and the existing sound bed.
Write to the timeline
Keep the script short enough for the video duration and leave space for visual moments, cuts, and on-screen text.
Mark pronunciation
Add guidance for names, brands, acronyms, product terms, and words that need a specific spoken form.
Decide replace or mix
Replace original audio for clean narration, or mix when the video still needs ambient sound, music, or source dialogue.
Use media you can edit
Only upload videos, music, and scripts you own or have permission to process, especially for client or public work.
How Add Audio To Video works
The tool turns your script into speech, aligns it to the uploaded video, and exports a narrated video file in the same workbench.
Upload the source video
Start from the clip that needs spoken narration, commentary, or a simple replacement voice track.
Write the voiceover script
Keep it concise and aligned to the clip. The page turns that text into speech before merging it into the video.
Choose voice and mix mode
Pick a voice preset and decide whether to replace the original audio or blend the narration on top.
Review the final audio mix before publishing
A good narrated video should sound clear, stay synced, and respect the rights of the source media.
Check timing and sync
Listen for whether narration starts, pauses, and ends where the visuals need it.
Balance voice and source audio
If using mix mode, make sure music, ambience, or dialogue does not overpower the generated narration.
Review script accuracy
Check product claims, pricing, names, calls to action, and any legal or safety language before export.
Avoid misleading voice use
Do not present synthetic narration as a real person's voice or endorsement without permission and disclosure where required.
Add Audio To Video FAQ
Answers for adding narration or generated voice audio to video.
Does this generate speech automatically from the text I enter?
Yes. The tool uses Vidrush text-to-speech workflow to generate narration first, then merges that result into the uploaded video.
What is the difference between replace and mix?
Replace outputs the generated narration as the main audio track. Mix keeps the source audio and layers the new narration over it when the source video already has audio.
How long should my narration script be?
Keep the script short enough to fit the video duration. Read it aloud once before generating to check pacing and pauses.
Can I keep background music?
Yes, use mix mode when you want to keep some original audio. Review volume balance so narration remains easy to understand.
Can I use this for commercial videos?
Commercial use depends on your rights to the source video, script, music, voice terms, and final platform rules.
