How to create an AI voiceover for a YouTube video
Start with what the viewer needs to understand at each moment. A useful voiceover explains the action or adds context, instead of describing every visible detail.
Outline the video before generating audio
Divide the video into an opening, the main steps and a closing. Put notes about footage in a separate column or document: text pasted into the speech editor may be read aloud. Give each section one job, such as introducing the problem or explaining a button.
Opening: ‘Here’s how to turn a written draft into a voiceover.’ Demonstration: ‘Paste your text, choose a voice, then generate the audio.’ Closing: ‘Download the file and add it to your video editor.’
Generate by scene
In TTSHub, open the studio, paste the narration and choose a voice. Use the same voice and delivery across related scenes. Start with the opening to check the tone, then generate the remaining sections separately. This makes a changed sentence easier to replace without regenerating the whole video. Keep each request within the editor’s character limit.
Match the edit to the spoken result
Download the generated file in its available format and place it on your editor’s narration track. Listen to the actual duration before trimming footage. If a scene is too short, remove unnecessary words or extend the shot rather than forcing an unnaturally fast read. Lower background music while the narrator speaks, check captions against the final audio, and review the platform’s current disclosure rules when your content needs them.
