AI voiceover video generator for business videos

The problem

Keep narration in the same edit

Recording voiceover outside the project adds another file, another timing pass, and another round of revisions. A script change should not force the team back to a separate audio workflow.

i.

A new line means another take

Small script improvements become recording requests when narration lives outside the video project.

ii.

Audio timing needs a second review

Narration, captions, and scene timing can drift when a revised track is exported and re-imported.

iii.

Language changes create duplicate work

A localized version is harder to maintain when its voiceover is disconnected from the source script and scenes.

AI Voiceover keeps the script, voice, and scene edits together.

The solution

Script and pronunciation in, revised voiceover out

AI Voiceover turns script text into narration inside the project, then lets you revise speakers, language, pronunciation, and affected scenes.

Completed Studio business-video scene about using a dedicated microphone.

Narration follows the script and the scene plan.

i

Script-driven narration

Write or import the script, choose a voice, and generate audio that stays attached to the video's scene plan.

ii

Speakers and team voices

Choose a voice for a single narrator, or select Conversation style for two or more speakers with distinct voices. Describe their roles in your brief. Approved custom voices can come from the team library.

iii

Tune and patch the edit

Set a custom pronunciation, change the language, or edit a scene's narration and re-voice the affected audio while retaining the visuals.

What makes AI Voiceover different

Voice changes follow the video plan

AI Voiceover uses the project's script and scene structure, so speakers, language, pronunciation, and revised lines stay close to the edit.

Script-linked

Uses the active script

The voiceover is generated from the same copy the storyboard and captions use.

Conversation-ready

Give each speaker a voice

Use two or more speaking roles with distinct voices. Set the lead voice and describe the remaining speakers in your brief.

Precise

Fix names before they ship

Add a custom pronunciation and preview it before generation, then re-voice a changed scene when needed.

Explanation

Give each speaker a voice

Conversation supports two or more speaking roles with distinct voices. Choose the lead voice, describe the others and request changes to a named speaker’s answer.

Questions about AI Voiceover

What does an AI voiceover video generator do?

It turns a video's script into narration inside the same project, where the voiceover stays connected to scenes, captions, and later edits.

Can I choose a voice or speaker?

Choose the lead voice in the composer or use an approved custom voice available to your account. For dialogue, select Conversation style and describe the other speakers and their delivery in Video brief.

Can I clone or upload a custom voice?

Yes. Custom voices can be stored in the team voice library with consent and used for branded voiceover.

Can I create multilingual voiceover?

Yes. Translate the script, captions, and on-screen text, then generate voiceover in the target language. You can also ask chat to change the voiceover language after the video is generated.

Can I fix pronunciation before generating?

Yes. Add a custom pronunciation for a name or technical term and preview it before generating the voiceover.

What happens when I edit one scene's narration?

Edit the narration in Edit → Script and re-voice the affected scene. ngram keeps the scene's visuals while applying the revised audio; larger timing changes can regenerate the scene.

Does AI Voiceover work with avatars and talking heads?

Yes. Generated voiceover can drive avatar and talking-head lip-sync workflows when the project uses a presenter.

Is the audio created inside the video project?

Yes. The voiceover belongs to the same project as the script, storyboard, captions, and scene timing.

Can I make a voice-only conversation?

Yes. Choose Conversation style with a compatible model such as Opus 5.5, then open Presenter and choose No avatar. Keep voiceover on. Describe the speaking roles and approved facts in Video brief, and ask for source visuals or motion graphics without visible presenters.
