AI voiceover video generator for business videos
Use an AI voiceover video generator that keeps narration in the project where the script and scenes live. Choose a speaker, adjust pronunciation, and revise the audio without starting a separate recording workflow.
- Generate narration from the approved video script
- Choose a speaker, including two-speaker Conversation videos
- Set pronunciation and language before or after generation
- Re-voice affected scenes after script edits

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.
A new line means another take
Small script improvements become recording requests when narration lives outside the video project.
Audio timing needs a second review
Narration, captions, and scene timing can drift when a revised track is exported and re-imported.
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.
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.
Narration follows the script and the scene plan.
Script-driven narration
Write or import the script, choose a voice, and generate audio that stays attached to the video's scene plan.
Speakers and team voices
Choose a voice for a single narrator, or use Conversation mode to give two speakers distinct voices. Approved custom voices can come from the team library.
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.
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.
Uses the active script
The voiceover is generated from the same copy the storyboard and captions use.
Give each speaker a voice
Conversation mode supports two speaker turns with a distinct voice for each speaker.
Fix names before they ship
Add a custom pronunciation and preview it before generation, then re-voice a changed scene when needed.
Re-voice translated scripts
Translate the script and generate matching voiceover for a localized version without rebuilding the project from scratch.
How AI voiceover works
Choose the script, set speakers and language, tune pronunciation, then patch the affected scene when the narration changes.
Choose the source
Use the generated script, edit it in Edit → Script, or bring approved narration into the project.
Set speakers and language
Pick a voice, turn on Conversation mode for two speakers, and choose the language for the narration.
Tune pronunciation
Add a custom pronunciation and preview it before generating the voiceover.
Patch the affected scene
Review the rendered voiceover, then edit a line and re-voice the affected scene while keeping its visuals.

AI Voiceover compared with the usual alternatives
AI Voiceover is built into the ngram video workflow. The comparison below uses conservative workflow categories instead of unsupported competitor claims.
| Capability | ngram | Manual workflow | Template editor | Point tool |
|---|---|---|---|---|
| Script connection | ● Generated from the active video script | × Recorded outside the project | ~ Often tied to a separate audio file | ~ Generated in a separate tool |
| Revision workflow | ● Regenerate after script edits | × Record another take | ~ Export and re-import audio | ~ Create a new audio file |
| Localization | ● Pairs with translated scripts and captions | × Requires separate recordings | ~ Requires manual coordination | ~ Varies by tool |
| Team voice support | ● Workspace voice libraries when approved | × Depends on available speaker time | ~ Depends on vendor setup | ~ Usually separate from video editing |
